I also have Briar if you would like to chat in a significantly more secure manner. As both parties have to be online at the same time, send me a message somewhere else, we'll exchange connection URIs, then coordinate when we're both available from there.
Despite the many ways to contact me, email, XMPP, and IRC are and always will be my most preferrered methods (as well as the most reliable). If you email me, please be sure to encrypt it with my GPG key. If you message me over XMPP, please make sure it's with a client that has OMEMO encryption.
