This is what I've been doing. :)
About... a week ago or so, I asked if it would be a good idea to join a challenge comm. As it turns out, it was a very, very good idea.
It's awesome. I'm part of Team Titans and I love the challenges. So far there's a word search (which I loved, I'm thinking about doing it again, only I still remember where most of the words are), two banner challenges (I'm learning about graphics!), and our first fic challenge (you know I like that).
In the same fandom, there's also:
It's cool - before you join, you fill out an application and your Godly parent is chosen (and you're given a nifty banner). You can then join a team and compete in even more challenges (but you don't have to). You can post fics, graphics, picspams, anything you want. It's great.
On a side note, I made both banners. I think I'm learning. :) click and they'll take you to their respective communities. If you know the fandom, check them out.
