If you mean swear words Michael, they should be filtered out by the forum swear filter.. Apparently, Its still not allowed to circumvent the filter like using characters like **@#$ etc..
Sometimes I copy/paste a joke from elsewhere and these characters are there from the original joke article..
Have to say that if I removed them then the joke would no longer be funny, or the punchline would no longer make sense.
Perhaps the joke thread should be allocated a moderator of its very own!! (but not me)

If you see a word that offends you, ask that it should be added to the filter.. See if they agree and add it!
When Steve typed
tw-t, I`m sure he meant TWIT and not **** BTW ...So that should be fine!
