I am working on a group project for a Library Technology project through Emporia State University, and one of the requirements is that we create a wiki for the tech documentation. Digging through the wikimatrix wizard I found a half-dozen free wiki sites that fit the criteria I needed (change history, WYSIWYG editing, etc.) and Wagn is the one that interested me most. I also appreicate that you use open-source software for your platform, being a split Linux/Windows user myself. If only the Zoom interface would work better with Ubuntu, I wouldn't need to be so fussy!
