I was thinking about the naming question and realized I haven't even introduced the wiki term here. Ups!
So let's go to Common Craft and let them explain it to you:
So a wiki is a web page anyone can edit. Maintaining link lists is a pain since they keep changing/disappearing but if there is a big group editing the wiki regularly the pages will be up-to-date. Collecting all dollhouse related links into one place is a huge effort but together we can easily make it. Go to Editing instructions to find out how PBworks is updated and start contributing by sharing your favorite links :).
