Okay, I decided to adopt the teachings of Pareto
and postponed a few of the more exotic and non-essential things.
This has lead to me finally making ground, and after finishing the user preferences page, which should happen soon-ish, there is only some feedback editing stuff in the user panel left and things should be good enough to wrap them together as a first alpha.
I know that things are still rough, the installer is acting like a spoiled brat and sometimes the db load is too high (will implement some cache stuff here), but apart from that it's pretty exciting - and scary.
I never published a program (a) that huge to (b) that many potential users, and yes, sort of scared.
Never the less, going forward, one stumble at a time
