I think several of the Stubs could be merged with other articles, so that the info isn't spread over several pages. For example, there's the article Tiigran-Merisst, a new species from the sadly defunct Teeth of the Tiger campaign - so I doubt that this article will ever be filled with much info, but it could be added to the TotT-demo article.
Speaking of that, most campaign articles are horribly outdated, for example MT, ED and BWO are still considered alive, despite having been declared dead on the forum (with last-edit around 2009-11). For the HLP-hosted campaigns, maybe somebody could contact the project leaders whether they want to have a wiki-presence? Exile and SG for example don't have one.
