Ex Isle Forums ^[1] Is something I am going to have to check out sometime in the future. Another time-waster. It’s a forum set up for sci-fi buffs. In their own words:

Ex Isle Mission: Ex Isle exists to provide a place for science fiction and fantasy fans to engage in civil discussion in their areas of interest, including science fiction and fantasy in all media, and also science, current events, creativity, and general socializing and fun.

It’s got some discussion, an area to publish fiction, and a community area. All total, there are 19 different categories, and at the time of this posting, some 815,000 posts from 1943 members. It’ll take some time to browse.
