It's Beginning to Look a Lot Like December Events

As you're putting your shopping lists together for the holidays and breaking out the winter coats (or the summer shorts, if you're on that side of the world), we have some more fun to add to your December plans:

- 2024 MOSTS will open for voting on December 6, 2024 at 2:00 PM (that's in 6 days if you don't like clocks), and run for a week.

- 72 Hours of Kaizo #2: One last little shindig for the year - we will host the second 72hoK starting December 13, 2024 at 4:00 PM. It wil be a themed contest, so don't you prework on this. Remember, Santa Thwomp is watching.

Community Contests Update

So it turns out that when we created the Community Contests & Events subforum, we forgot to enable regular users to make threads.

So if you've had a contest idea burning in the last....uh......4 months......you are now able to post them in the subforum now.
