The ONLY true wiki solution for SharePoint
Those looking for wiki solution in SharePoint knows the OOB Wiki in 2007 and 2010 is a (bad) joke.
We have been using this tool on 2007 and recently upgraded to 2010.
Our users ARE wiki users - they work with other wiki solutions, they use wiki markup and not just rich text editors.
If they are happy - I am happy.
And with this product, they are very happy.
Support: We had few issues, none were major. We got workarounds within few days (2-3) that we are happy with.
We did not have any major issues with this product, and the vendor releases updates regularly, which is making support plan a good investment.
Integrated very well within SharePoint.
