One For All vs. All For One
Would you rather have each sig (or group of sigs depending on the timeframe in which they were made) receive their own thread for C&C, which is the way any other site regardless of its main purpose uses a "Creative Works" forum for. Or would you rather each member got ONE thread to post all their work in.
I know for a fact that it works better and is much more focused if each piece of work gets its own thread and considering how small the artist community is on this site I don't see how spam or anything else could become a problem. Lets not even delude ourselves into thinking that this forum is currently active enough that threads will be bumped off the first page or never be seen because of the alleged speed that the threads will be posted.
