This is a community project - you'll only get out of it what you
want to put [back] into it.  So, instead of sending multiple nagging
emails [about the same thing], why not propose some patches?  You've
obviously looked at the code, docs, etc - it seems only fair that
you help out.

Persistent complaining without pitching in will probably just
turn folks ears deaf...
