many times you want to open a forum and it is relevant for 2 different forums. i think you should open a place when you can open you thread and a moderator will move it to the right place. i once got bumped because of it. what do you think?
No. The moderators have enough to do already - well, the regular visitors anyway! There's also a concern that some members simply 'won't be arsed' to make the effort to select the correct forum in the first place, choosing instead to dump their thread in this free for all forum you're proposing.
You can always PM a mod or ask in this section if you're unsure. No one will give you an infraction for asking. (I believe)
