By that logic, Thiamor, renaming the anime and manga boards to animation and comics was all for naught as well. The whole reason for that was to leave that first impression, in the case that they didn't read.
We do say that if they don't read they are inherently stupid for not understanding a basic concept, but we're allowed to help them understand as well. That was the whole reason for things like the FAQ thread, the board descriptions, and the additional topics in the first place. That said,
>>11 is a legitimate counterpoint to the suggestion, along with other things that have been said.
I think general consensus, in any case, is that a fanfic sub-category is not needed at the moment, if ever?
