FogBugz wikis are an easy way to collaboratively maintain documents within an organization or project team. You can also open them up to a wider audience and leverage the easy setup and use for non-FogBugz users. You can keep publicly-accessible end-user documentation in them or setup status pages and reports for your clients.
Wikis have separate permissions settings for internal FogBugz users, registered community users and anonymous (not logged-in) users. To set these up, click Wiki | Customize... and then click the Configure icon next to the wiki.
You can set a wiki to be readable and writable by any logged-in FogBugz user. You can then choose whether community users who have confirmed their email addresses have read-only, write or no access. Lastly, you can set the permission level for anonymous users.
If you need finer control over which FogBugz and community users have access, just select a group from the drop-down menu. You can setup as many groups as you like. Each one sets read, write or no access for each FogBugz user. You can also add community users to a group, granting them read-only or read and write access. Since community users require email verification but don't use up a license, they provide a good way to give individual clients access to project status pages without letting them see other projects or having to open your pages up for access by anyone.

From the same customize page, you can select which template to use for all pages within the wiki. Editing the template lets you set the HTML of the page, using template variables such as $headline$ (the article's title) and $body$ (the content of the article) to place the wiki and article-specific content. All of the format and styling of the page can be controlled through the template's CSS. Together, these let you make your wiki exactly match your company's website layout for a seamless experience for your community.
