Well, I post in the Adult part almost every day - every other forum I belong to, whether its to do with Chickens, downsizing or therapies, ALL have a section for humour and sillyness - also for quizzes and other light hearted things.
I strongly believe we all need to have a chuckle and lighten the mood every once in a while, it doesnt hurt anyone; and lets face it, it does have a warning that comes with it.
Check out some other forums, see how they are run, I think you;ll be surprised to find that 'The Other' place most of us from here originally came from is in the minority.
However, if the general concensus (is that spelt right?!) says they dont want it, fair enough.
