I am noticing moisture around the bottom of the toilet, and can tell some moisture is staining the wood floor when viewed from the basement. The bolts holding the toilet are easily tightened.
Will that help or should I just replace the wax ring?
UPDATE: When I got the toilet ready to remove, drained it, turned off water, removed as much water from drain as possible. I started to undo the bolts holding the toilet in place. I noticed they were VERY loose. Since I could hand tighten the screws, I decided to just tighten the bolts a little and see what happens. So far (3 days) no leaks. I am surprised but will monitor it for awhile I'm sure. Feeling lucky.

Before you start verify that the supply line or tank isn't leaking , dripping down the back of the bowl and flowing around the base. If that looks good I would pull up the toilet and at the least replace the wax ring. I say at the least because most times the bolts get loose for a reason. It may be a cracked flange, broken bolt, rotted floor etc. You have no idea how long it has been leaking before you noticed it. By taking up the toilet you can examine the flange, the floor, the subfloor and the bottom of the toilet to determine the cause of the leak. This will allow repairs to be done in the earliest stage. It will be easier to repair the flange if that is the issue then to wait and have to replace a piece of rotted subfloor.
