This is the Solstice Wiki.
You can create static pages for characters or places / items of interest, and also create blog postings. Both pages and postings can have comments added by other users.
To edit or add material, you need to first be registered – user the sidebar logon to do this, then have an administrator elevate your permissions to allow authoring / editing of material.
Admins get notified whenever anything is changed. They also get notified of all new users.
