Some of you may have already heard about this, but it just came to my attention and I thought I'd let everyone know. FictonAlley is running a competition asking people to write or draw things about their community experiences and thoughts about PoA. The idea is to "creatively express your perspective on seeing Harry Potter & the Prisoner of Azkaban as a member of this Harry Potter fandom," and that sounds like fun to me :) Prizes for winning entries include things like a Trelawney tea set, time turners and other official HP merchandise.
The contest ends on June 15 which is in three days (!), but there's still time to submit something. I'll be putting something in myself, if I can find the time!
You can find the full details of the contest here.
