It's nice to be notified about it too, so please send me a note if you use anything.
I reserve the right to request you take anything down that I find objectionable, though as I'm into hypnosis, objectification, dollification, mind control and other fairly odd topics, unless you're doing something *really* horrendous, that's fairly free reign. ;)
All the best!
