I found the docs for plugin writing to be a little lacking.  In some 
cases, I really had to look more at what other people had done ... some 
of which was done poorly, or done in ways that were done with a very 
short-sighted approach (one plugin was processing _all_ configuration 
options, and rejecting ones it didn't like ... including _my_ 
configuation options, because they didn't read the part about how to 
properly say "this is someone else's config option").


So, anyway, if you have any questions, feel free to ask.  I've been a 
bit busy lately, but I'd be happy to pass on anything I managed to learn 
while writing my plugin.  (and there's still a thing or two I want/need 
to learn for mine)
