"7) Why was it so important to release Roundcube as a free, open source project? What advantages does it bring as opposed to using an ‘opencore’ business model?
"Open source software is a very important part of Roundcube itself and we wanted to contribute something back to the community. The main advantage for us is that the software is provided “as is” and we don’t have to provide support or responsibility to our “customers”. This may sound a bit rude but all of the core members of the Roundcube team are volunteers working on the project in their spare time. We all have our jobs beside Roundcube and therefore we cannot provide real-time support or immediate fixes if a problem occurs. This is something people would expect when the pay for a product.
"8 ) Can users try Roundcube without doing a full installation, to just to get a feeling for the capabilities?
"No, we currently don’t have an online demo ourselves. But on the Roundcube forums, there are always a couple users who run demo sites."
