There are some levels to this... Which of the following question types do we accept and which do we reject as off-topic?
- Recommendations for which web app software to install - not technical questions, just recommendations about features etc (such as this one)
- Questions about how to enable certain functionality in a web app installed on their own server
- Questions about technical issues with installing a web app on their own server
I'm pretty sure we should rule out the last one, but not so sure about the other 2...
