I need a 100 forum posts. So may as well talk about the blue building I guess. Also need about another 100 and something achievements... going to be looking for those to accomplish.

one of the easiest place to get your post count up is the Games Forum. You play your games/activities, then post your results in the appropriate thread. You don't need to fret about coming up with stuff to talk about. If you're shy, it really easy posting.

Another good place is User run games. There's easy stuff, like TV Shows a-z, names a-z, etc. that again don't require a lot of investment in figuring out what to say.

NOTE: making thread does NOT add to your post count, you need to reply/respond in existing threads to have it count :)

There are a lot of tiered achievements that the higher tiers are difficult (or time consuming, or expensive), but the lower level tiers are very quick, easy and cheap, so you'll want to look at those :).

You can also take a look at the other threads in this forum - stuff like lending for achievements, you've got a friend in me and so forth can really help with your achievement goals.

Good luck!
