I noticed that Neocities itself and Neocities subdomains (including mine) weren't appearing in Bing search results (for me at least). I contacted Bing Webmaster Tools support and explained that Neocities is a web host and each subdomain is a separate site with a separate owner. They got back to me and now Neocities+Sites appear on Bing. Yay!
I'm considering making an "old fashioned" forum for my site, using my user account system. The idea would just be a chilled out place to discuss games, web development, TV shows, or anything else really. I'll probably make it anyway just for the fun of coding it xD, but just wondering if anyone would join?
