After having a browse of this Wikia, I've noticed that it contains certain homebrew rules presented as if they are official. I'm not against homebrew at all, I just think that it would be best if it was clearly labeled as such to avoid confusion. I've also seen 'may be taken with GM approval' used alongside homebrew species, when that isn't a rule in any of the books.
To give a specific example, the Classes page prresents two classes based on previous editions of the game as being 'cut classes' that were almost published. Looking at the writeups given for these classes it is clear that the're not unpublished draft versions as they have access to talents and feats that only exist in the later books.
Again I'm not saying that there is anything wrong with designing new classes, I just think that it's misleading not to inform people when things aren't official.
