It is perfectly possible to contact me.is preferred.
My preferred email address (for most situations) is: harrismw(@ ]next-nexus( .(info.us (strip all the whitespace characters, () and the final .us). In the event that next-nexus.info is down, you can also try michael) @)sequt (.]net.us, but don't use that as an email of first resort; I rarely check it. (Please don't continue to use my old Yahoo email accounts: they are also unlikely to be checked as fast as you would prefer; and I am phasing them out. Please don't use any university or IDS/TUCS email addresses you might have, I probably no longer have access.)
I have an OpenPGP key, please feel free to use it (more info about OpenPGP). The finger print is DF3B EF2D E60F FBF1 921E D0C0 A52F E9B4 8864 8388 (size is 4096 & type is RSA). My key is also on keyservers, such as Ubuntu's or MIT's.
Any other method of contacting me is not a sure way to find me. After all, my phone number changes often, as does my address. I only sometimes use IM tools, and similarly IRC. I do use VoIP (sip:firstname.lastname@example.org), but require that a time be prearranged, because otherwise I don't run the software. I may also use other VoIP systems (like Skype) but, again, prearrangement is required.
If you would like me to do some web work, or read something, say customise WordPress, or perhaps install and customise Generic Tables, well email me with what you would like done. Everything on this site was written by me, except where noted. That should give you an indication of what I can do.
