Take a look at PBWiki (pbwiki.com). It uses Wikipedia-style pseudo-code for editing pages (instead of Jot-style WYSIWYG editing) but it’s otherwise very easy to use. It also lacks the plugin apps (calendar, spreadsheets, etc) but it doesn’t sound like they need those.

On the plus side, it’s hosted (at least I consider that a plus) and allows customizable CSS with the enterprise version. I personally think Jot is ugly. And it does away with those infernal “WikiWords” - I deployed a Jot wiki at for my company about 6 months ago and I still have to explain WikiWords to somebody once a week.

For whatever reason, they don’t publish a version comparison on their main site - it’s only available when you want to upgrade an existing wiki. Here’s one from someone else’s wiki: (https://walkinguofmclasses.pbwiki.com/upgrade.php) If you want domain mapping you’re stuck with Platinum.

PS. I’m not sure if Ian called you yesterday, but I’d like to talk to you this weekend. If you could shoot me an email and let me know when you have about 20 minutes to talk, I’d appreciate it a lot.
