In addition to the various contact forms listed below, you can send me normal email with a normal email program. Send it to T.Rex-2021 at this domain. (Sorry not to put it together for you, but I don't like spam.) That will work for this year. Next year, it will be deprecated in favor of one made up for that year. The following year, it will be shut off.
If you're not just telemarketing, you can also call me, at +1-571-308-6622.
Lastly, I can also be reached via Skype. However, don't usually have the app going, so you'll have to arrange it in advance.
