You may now purchase days of Hero time on the Die2Nite website.
There's also another way to become a hero: manage to pull out of a town that has lasted for five complete days as the Last Man Standing, and you'll be rewarded not only with a special distinction but also with a certain amount of Hero days depending on how long you survived. You can read up on Last Man Standing and the rewards here.
Be Active!
One of the best things you can do is to make everything as
simple as possible for the rest of the town. One of the easiest ways to do this is to make sure the stickied threads stay
on-topic. One of the easiest ways to do
this is to start off by making a bunch of other threads for specific purposes. Here are some examples to get you started:
An Expeditions thread, to be updated daily. Here, your town can organize its expeditions each day.
A Daily Summary
thread, where you or others can post
a brief summary of the previous day
each morning, for those who might have not had a real chance to get involved the day before, and want to know what took place (i.e. what was built, found, important descisions, etc).
A Town Ranking thread with a link to the Leaderboards. Here your townsfolk can compare your own strategies with those of other towns.
Discussion Threads for Construction, Town Upgrades, and Workshop threads. By separating the discussion, you can leave the Stickied threads for simple instructions based on what is decided in the discussion threads. Less active players may find that much more useful than sorting through pages of discussion on the main thread to find out what they are supposed to be doing.
A Water Discussion thread. This one is very useful.
A Resources: Current Priorites thread, to discuss what items townsfolk should be choosing over others when scavenging.
A Gate Duty thread, for townsfolk to decide who will close the gates each night. To be used daily.
A General Chat thread. This allows your townsfolk to get to know one another, and also keeps this chatting out of more important threads, like the Bank, for instance.
A Complaint thread. Yes, this one is important as well! Each banished citizen is a waste of a minimum of 12 ap every day. Banishments should be avoided if they can. This thread can be used for citizens to work out their differences, or explain actions that may have caused other residents some annoyance.
Remember, the earlier you set this up, the better, as doing so will avoid a greater confusion of inane threads towards the beginning of the game. Try to get some of the more influential townsfolk to use the threads you create, and encourage them to create their own general threads like these, and (mostly) everyone else will follow suit eventually.
Another important thing to remember is to clearly state in each of these threads, that they should be used as stickied threads, daily. It makes much more sense to have one gate duty thread used every day than to flood the boards with 2 or 3 new ones every day.
This will obviously not work for every town out there, but I have been in towns where others have done similar things, and I've tried to do something of the sort in my current town, and the results are good enough to warrant giving it a try, I think. The trick is to make everyone else think you know exactly what you are doing, and they will tend to fall into step behind you.
Also, make use of external applications!
This Map is particularly useful, because it lets you list exactly which items have been left at each place on the map, as well as listing the number of zombies, and townsfolk at each space, among other things.
Fair warning. The tricky part here is that links to these services go against the linking policy. Your post, if reported, will be removed if you link to those pages. Please read the "RULES & MODERATION IN TOWN FORUMS" thread in the world forums Help section for more information.

Expeditions are what you make of them.
You can create an expedition from Town Gates → Expedition. From there, click on the map to make waypoints, name your expedition and save it.
Alternatively, you can select an existing expedition from the map interface.
Now, when you'll be in the world behind, a small arrow will point to your next waypoint, making it easy to follow the path you defined.
You only need expeditions if your trip is complex (e.g. to work around zombie infested areas) or if you are travelling in groups. Group expeditions should be planned on the forums (or on whatever other communication channels you have); otherwise, you should assume that the plan has no particular use and you should ignore it (or use it to explore a different path.)
