Well, I'm an admin here, on thunix.net. Feel free to hit me up via email or irc. I'm generally a friendly guy :) I might take a bit to get back to you, don't be offended, I sleep sometimes, and have other things happening as well.
My public key can be downloaded here. I try to sign most, if not all, of my thunix mail with my key. If you doubt it came from me, ask me to sign the email, and I will.
