Maybe instead of the old "Make Thread" button where you only type in the title, how about a button that says "Create Thread", then you click on it to type in the title and the description.
For example: If I made a thread saying "What would you do if...", then I had a lot of text to type in, it would take a while. So I type in the title and post my thread, then I go to make a description. And then when I'm done, someone might have already said "Why haven't you given a description? -_-". If this happened, then I'd be able to write a description before posting the thread.
Well I would like it to machine guns and a a hover device ohh and when i talk into the mic for it able to understand what im saying so it types for me. and the last this is for it to read my mind ...
