The main aim of the forum is to provide a communication link between PVsyst users.
If we have taken the habit of answering many questions, it is not an obligation.
I was personnally very busy these last weeks, so that I indeed neglected this channel.
When you have specific questions (and especially bug reports) the normal channel is our support@PVsyst.com
NB: I don't understand well the assertion "No proper documentation for updates". It seems that we do our best for documenting the evolution of the softtware, with the release notes, the help, the FAQ, some tutorials, etc.
