I'm still on the same regarding the little project I started.
I got in contact with Martin Konold of KDE and he said he'd give me write access to the kde-core-devel mailing list. Well, I don't know if he got to that or not, because my e-mail seems to be filtered out of KDE's mail server. (must be a rule regarding @mail.com)
So, I'm still waiting for an answer, and it seems people are going on vacations already
