Outlined below are the best methods of reaching me. They are subject to change.
For matters that aren't time sensitive, e-mail is the best way to reach me. I check my e-mail when I feel like doing so, and will probably respond within a week. If it takes me longer than a week, then I may simply be taking a break from computers. Please sign/encrypt your messages using GPG if you are able to.
If you'd prefer to chat over XMPP, e-mail me and we'll schedule a time to do so.
