I'm all for the blitz to come back even though I only finished one fic for that, haha. Prompt challenges are fun too (and perhaps a good way to get back to Pokemon fanfiction).
Your post does bring up an interesting question as to whether the prompt challenges would be Pokemon fics only. On one hand, this is a Pokemon forum. On the other hand, the fics aren't being judged like they would be for the SWC, so it's not like they need to be Pokemon-based to get reviews. It probably helps though.
So either the amount of reviews would have to be dropped rather low, or else the review challenge gets a break in December. Either way, it's fine by me. Or we could even fudge up the schedule a bit and do the review challenge in January or in another month that was originally an "off" month.
