I am a KDE developer, my most widely known program being KRN. After a long hiatus I restarted development a couple of months ago, after I decided the current state was a bit embarrasing.
Don't get me wrong, I am not embarrased by the program as a whole. After over a year of zero development, it is still one of the more full-featured GUI newsreaders you can find, and I basically learnt C++ while writing it (and it shows ;-)
So, now, after returning (a mere 5 hours ago) from my vacations (nice, beach, sun, etc.) I will try to hack 0.6.9 out as soon as possible.
There are a lot of nice things already done (how about "select from Article where Sender like "%@my-deja.com%" and Date > (TODAY()-3)" ? And no, you don't need to install MySQL for this to work!
