The Contests forum has now been moved from News to Calculator Community. In addition, there is now a "community contests" subforum where any of your own contests/challenges can go! Good luck to everybody in all the contests sure to follow!
While your at it, check out
Code Golf - The Reboot. It's a reboot of an old series of contests done by JWinslow23, now done by pimathbrainiac (and others in subsequent iterations).
Since this restructure started due to a discussion specifically about Code Golf, the new moderators of the new community contests board will be JWinslow23 (who started Code Golf), c4ooo (Who prompted the restart of Code Golf), and pimathbrainiac (Who actually restarted Code Golf). All three of those listed, as well as some of the current active members, will be posting the weekly Code Golf here on Omni. For those who don't have an account here, that's fine! If you want to participate, send your solutions to the week's Code Golf organizer via IRC or another site. If you can't contact them, contact one of those listed in this post, and your solution will be passed along. More information can be found
here.
