this is probably something best left in the Chatterbox or Comic Creators.
unsolicited advertisements/plugs/promotions generally aren't allowed in most sections of the forums, especially not in sections intended for discussion. plus the AMC is specifically for discussions related to professionally released works.
if this was your own work you could post about it in Promotions, but since you admit its your sister's work it wouldn't belong there since Promotions is for promoting your own works/sites/whatever.
also, it may flat out be best if you use your sig to promote it, as more people will see it and posting the same or similar thing in multiple parts of the forums is spamming and can get you in trouble. you're only supposed to make a thread one time in the most appropriate section of the forums.
Sorry! Im new to using forums!
that's okay, everyone can make mistakes when new. altho that's also why it's generally suggested one lurk a while and/or read any FAQs or R&G info before making threads of their own, sticking to replying to existing threads and getting the hang of things first. there may be some things "I'm new and wasn't aware of that" can get you some leniency on, but there are other things that won't work with and you can find yourself getting a formal warning or even a temporary or permanent ban for.
