<p>I'd like to suggest that this wiki install Semantic MediaWiki, a MediaWiki extension that allows for semantic data to be stored and accessed within articles. What does this mean? Well in situations like the issue described here by Alemas2005, Semantic MediaWiki would allow for data such as a user's name, rank, and avatar to be stored on the user's article, and then be accessed using semantic properties on another article such as a song or band article. So an example of this in use could be on a song article, where the song was written by "User1234" but you want to get their avatar, instead of having to manually add it and update it manually any time it changes, you could do {{#show:{{{1|}}} |?Avatar}} where {{{1}}} is the user's name, and "Avatar" is a defined semantic property used on the user's article. </p>
