Hi,
I'm still a rookie with Geeklog but never the less in general there are a few things I've stumbled upon which could be fixed fairly easy, but it would require community support since it's allot for just a few persons.
As the subject stats, I think it would be good to centralize documentation related to Geeklog. On Geeklog.net there is a nice
wiki (Media Wiki) which is already full with allot of information but I also noticed that e.g. the
French Geeklog site has allot of English documentation inside their Wiki (DokuWiki), great stuff Ben ^_^, and regarding to plugins information is allover the place, e.g. Navman which still works with Geeklog 1.7.0 has a very good English document, but that document comes with the plugin and all other information for that plugin is in Japanese (I love Japanese but I can't read Kanji

).
So consider this feedback or a call to arms ^_~ Either way, I think it would be a good start to start filling Geeklog.net's wiki with whatever information you can find.
Getting an account for the wiki isn't that hard, check this link for requesting an account:
http://wiki.geeklog.net/index.php/Special:UserLogin
It basically asks you to send an e-mail to Dirk, Blaine or Vinny.
And if writing isn't your main thing then you can always PM me a website or article and I'll help add it to the wiki (I don't mind writing).
So let's get to some documenting 8)
p.s.
Wouldn't it be a good thing to use DokuWiki instead + use the plugin to integrate it with Geeklog? (e.g. how they did it at geeklog.fr)
It would require some effort but in the end I think it would pay off to have the site and wiki nicely integrated, the features that this plugin comes with are pretty useful (especially the search integration).
But that's just me thinking out loud.
