grow your wiki
Since a wiki thrives on activity, it's important to make sure the front page shows that and doesn't look stale. Some wiki software has the ability to display a list of recently updated pages, or maintain a dynamically updated list of pages labeled with a common tag.
Use an automatic index to keep your wiki homepage constantly and automatically updated as people edit existing pages and add new ones.
The Wikipatterns homepage has link to [Adipex Consumer Drug Resources] which shows automatically updated lists of the most recent edits and people who have contributed.
