I've been doing a Halloween blog-a-thon for as long as I've been blogging. It's my favorite time of the year. I think I've got it covered this year for at least one post a day during October.
If you're holding a month-long blogging marathon in honor of the Halloween season and would like to be included on the list, see this post here. Though there aren't any official rules, we do suggest trying to post frequently about some aspect of the Halloween season during the month of October, as well as spreading the word about the countdown.
