Most (if not all) requirements or suggestions that so far came out of the questionaire will be possible with the full version of vbwikipro (we currently run the lite version).
[ul]
[li]Administer wiki permissions and groups from within vBulletin’s Usergroup Manager.[/li][li]Full skin integration. No need to customize your wiki skins. Simply install vbWiki Pro and your wiki will inherit the look and feel from your forums’ styles and templates (including images, menues, colors, etc).[/li][li]Support for vBulletin Templates. You can further tweak the layout of your wiki pages by customizing templates in vBulletin’s Template Manager. No need to edit a PHP skin.[/li][li]Adds custom control panel to vBulletin’s AdminCP, where all vbWiki Pro and most MediaWiki settings can be configured. (Once MediaWiki is installed, there is no need to deal with config files whenever you want to configure your MediaWiki installation).[/li][/ul]http://www.nuhit.com/vbwiki-pro/features.html
I’ve looked for alternatives, but that one seems the best option.
