When we were in our product development cycle, we decided to host all of our customer documentation in Confluence.. We decided to create a single account called "customer" and then give that to all of our customers so they can access our documentation..
Problem is we now want to control that process a bit.. So were faced with buying a confluence license for each customer (ouch!!) or moving everything to a different type of wiki...
Have others faced a similar dilemma?? what choice did you make??
