dont worry matey, I wont be running in head first. Have to say on the old hosts the bandwidth wouldnt of been an issue as it was a silly figure, will have to check with my brother what we get on our current hosts.
My main concerns are people hosting irrelevant stuff, but my main plan is just to allow people to attach pictures to their posts only in the How - To section, and only on how tos (ie if its not relevant it gets deleted.) I do need to get in there anyway and have a clean up.
If there were any need to delete images for space reasons I would back them all up before hand!
Im aware of potential problems, which is why I havent rushed in.
Thanks for the input though, its always good to have everything out there
