Global storage in Guild Wars 2

Hi you should check out Massively's series The Road to 50 which goes into some depth and highlighting the easiest/more difficult statues to unlock. For me the easiest ones have been armour and minipets. The Skill hunter titles are loadsa fun and easy to get (4 titles with the Legendary one too). Sunspear points title is fairly easy, each of the Hero/Guardian ones are pretty easy to get too. Prices of a lot of materials have really shot up as a result of the HoM link, so beware. Don't buy now if you don't have to.

Please, remember to have fun. Nothing is worth boring yourself for. Grinding for titles/achievements is pointless if it's not fun.

You do not need a charter or to go to a special area, though you can create a guild by speaking to a Guild Registrar in a city.

You will need to have 1 silver in order to create a guild. Then all you need to do is open the Guild window (G by default), choose a name (31 character limit) and guild tag (an abbreviation that will show up next to your character name, up to 4 characters), and that's it.

Note that guild members don't even have to have be on the same Home World (server) as you, though you do need to be on the same Home World if you wish to play World vs. World together.

The default maximize size for a guild is 50 members. In order to increase this size, you will need to speak to a Guild Registrar. The following table from the official wiki lists the costs and upgrades as follows:

Tier   Membership Cap    Cost
 1          50         1 Silver 
 2          100        1 Silver
 3          200       10 Silver
 4          300        1 Gold
 5          400        1 Gold
 6          500        2 Gold
