"It has to be a sig that we can reasonably accept would appear on the KMC forums. Tgis cinludes many common sense things like it most likely having a link to one the the movies covered here, and CONTAINING YOUR NAME. More importantly, though, it must be G-rated, no profanity, or nudity, and so on."
Read the rules guys 😉
Sorry, you can't use your existing sig; it has to be a brand new thing created for the competition (the judges have to be satisfied that it is reaonably different from your existing one).
I don't think it is utterly impossible for the sig to not have your name on, but bear in mind it is a 'signature' after all. There have been nameless sigs around here before but nearly all of them do have the name on, if yours does not it risks dismissal on the grounds of it simply being a pretty picture, rather than a dedicated sig.
