One follow up question, since rpg is not under role play anymore, does rpg posts count as role play towards the achievement?
I am implying that I hope it does, and also I think rpg belongs under role play category more than game category, at least how I play role playing games, it is definitely more role playing (writing) than roll playing (rolling dice), and that I still think role play belongs in both games and fiction/writing category, and that includes the rpg tag.
It would be great if tags under a tag did not have to drag that primary tag with it, so that one could just apply the specific tags that make sense to a thread, but I am not sure that is supported.
Also not sure if the tag hierarchy supports many to many mappings for tags, I know that is a bit more complex to do in a database (require one more table, two total, instead of one to implement tags then).
