I'd like to implement a small random-number generator in BBCode, but I'd like to know if this is even possible before starting. Is BBCode Turing-Complete, and if not, are there any text markup languages that are Turing-Complete?
Watch it, Goy. You don't want to be sticking your dick in the hornet's nest now. Just accept that you can't use BBCode and move on. Some knowledge simply shouldn't be known to the public, and you wouldn't want to have something bad to happen to you, right?
