List of competitions

I was wondering if anyone had a list of competitions. I’d like to know when the next comp I can enter is: I think something official like a competition would motivate me to actually finish something instead of going through dozens of ideas, coding a few lines of each, and then giving up and deleting them. So, does such a list exist?

(It is worth noting that the competition would have to be totally Internet-based. I’ve heard of some competitions at IF conventions, which I couldn’t participate in.)

There’s a list at IFWiki: http://www.ifwiki.org/index.php/Current_events#Upcoming_Competitions. The list keeps up to date quite well. Most, but not all, comps are announced at RAIF.
