I want to see a "Artist Watch" option, so when someone posts something new, we'll know when we "Add to Favorites". Some people are very good artists and either don't have the time to animate all day, or they only update some very high quality work every once in a while.
I think this would really help out a lot of people here on NG, especially when you're waiting for new episodes or work from that artist. This is even better for new artists as well.
Now, the thing I would like more than anything in regards to the BBS is the ability to edit a post... When doing collabs, when things change, we always get people joining in late who don't know the new rules or changes made to the collab as a whole. It's so frustrating to post up how you would like the collab to be structured, only to change some settings, like resolution size, two pages in. Most people don't read everything to see if anything was changed.
