I'm @brittagus, and I work on community and support for SaurikIT. This includes contributing to this wiki and helping others contribute to it.
I've written the bulk of these articles: Advice for new developers, Tweak DRM#Practical advice, Career advice, WinterBoard (advice on how to contribute to it), How to use IRC, Open Source Projects, List of development blogs, Main Page. I like giving advice and helping people find things, apparently.
I also help with JailbreakQA, /r/jailbreak (as "beetling"), TheiPhoneWiki, jailbreaking-related IRC channels, informational text inside Cydia, and other things that make Cydia and jailbreaking better.
