(I'm positive someone suggested this before) I think we should be able to lock our topics when we want people to be able to read the thread and the comments on it, and don't want people to post on it (for whatever reason, everyone's would be different I'm sure.) One reason I could think of someone asked a question (pre answers section) and someone answered their question, and they don't want people posting on it (for their own reasons). They could click the edit button, on the edit page, their could be another button that says, "Lock this thread." Click that button would lead to a page that said something like, "Are you sure you want to lock this topic?" If they clicked yes, it would be a locked. If they clicked no, it wouldn't be locked. If they ever change their minds, they could un-lock it the same way they locked it. (Click edit, press unlock, and click yes, unlock) Thanks.
