In case you didn't know, it used to be that only the PMs you received counted towards the 2MB limit on how much space you had in the overall messaging system. Then, in the past couple of weeks, Newgrounds changed it so that you have 4MB worth of received PM space and 2MB worth of sent PM space, presumably to discourage spam.
Anyway, I'm currently about 3.5 times over capacity on the sent side (6.7MB vs. 2), so that's why I'm using a news post to tell @Dursope that the next NGUAC starts in June, but he should check the audio forum occasionally because other contests and events happen all the time! :)
I'll definitely have my PM outbox cleaned up before contest season, lol. Until then, please comment on this news post if you need to HMU.
