I have been here and there in different fandoms, whether anime, celebrities, or even hobbies, I have been eager to connect with others. However, as of recent, I have found that I can support those fandoms by contributing articles to FanHistory.com. FanHistory is a wiki that contains thousands of articles on different fandoms like actors, politics, sports, television, music and more. In fact, the number of articles total well over 500,000.
The great thing about the site is that if you are a fan of something, your article submissions are welcomed. It is fun and a way to connect with others. For those of you who I know run fanlistings, you could even submit your fanlisting within your fandom there. You just go in, register, find your niche, and insert your information on the pages of your fandom. You can even create a new page if your fandom has not been covered or if there is a part of the fandom not mentioned, like in anime, it could be categorized down to the character. Also, if you have a fanlisting, it could help you get a good reciprocal link.
In fact, I encourage you if you are a big fan of anything in particular, go to FanHistory, look up your fandom to see if it is listed. If it is not, you should add something about it. If it is, well, you can add more if there is anything missing.
