Surely this is obvious, but just in case: email@example.com.
These things are totally out of control and it's 95% redundant, but I'm a sucker for connections. Life is relationships. Care to share in the misery?
I am not on MySpace.
If you need to reach me online immediately, then your best bet is to private message me on IRC. I'm most likely to be online as "Nugget" on irc.distributed.net. Alternately, I'm reliably available on SlashNET and openprojects.net.
I'm not reliably connected to Skype, but you can give it a shot: davidmcnett.
Do I owe you money? Do you owe me money? I use paypal as firstname.lastname@example.org and can use paypal to exchange funds. At some point I managed to get flagged as a "pro" account, probably so I could receive a credit card payment from someone, so paypal takes its pound of flesh from all my transactions. Still, don't let that deter you from sending me money. :)
