Contact
Twitter - @dosmeow
If you want to contact me, the best way to ensure I actually see it in a reasonable timeframe is either DMing or just tweeting at me.
Mastodon - @sugar@chitter.xyz
I can also be found on the Mastodon instance Chitter. I visit this site a far more healthy amount that Twitter meaning I might take a day or even two before seeing a message sent to me there.
E-Mail - doctordos@gmail.com
If you must, I can be sent a plain old e-mail. Note that I don't check my inbox all that often.
Others
I'm also on other services, but I'd rather not be contacted by strangers who I haven't interacted with elsewhere first.
