I have been using gphotoshow for several years now and I just wanted to say how awesome it is! I am really glad you finally started your own support forum so I can listen to what other people have to say about the newer versions, and decide if it's worth upgrading. I still have 4.7 and I'm quite happy with it.
Anyway, the only suggestion I have about this site so far is that maybe you could put a link to the gphotoshow downloads page at the top or bottom of this page. That way people who visit the forum can easily jump to the website and see what other products you have and what version they are.
Thanks!
