The forums always have one thread where a person asks if they can transfom into a vampire, werewolf, or something else. I have never seen a person with anyone with a reputation level answer that it is possible.
I think to save time someone with a knowledgable rating should pin a thread as to why this is impossible along with alternatives to people who want some connection to vamparism or a wolf (Totem animals, energy vampires, etc) to the general information, spell suggestions, and site spells threads. It'll save lots of time and it can be informative and if written properly even satisfying for peopel looking for these kinds of changes.
Another idea, is that there should be a list of the most common magical traditions and paths, with links and resources on how to get started. And it should all be in one place
