Sorry the forum software doesn't support turning that off. I thought it did but when limiting the number of nested quotes it simply threw an error when you try to post with nested quotes that exceeded that limit ... which is pretty annoying to force people to have to edit them out. Some people just don't quite understand the quote tags so that would simply stop them from being able to post. Like Dennis said if you do understand the nesting of the tags you can just edit them out yourself. Sure it's a pity it's not automatically done for you but there is not much I can do about that. Maybe that will come in future updates of the software. I will submit it as a requested feature on the UBB Threads website.
