"Contact" can mean a few different things here-- contacting the LGN community itself, contacting a person in it, contacting the sysadmin, etc. etc. Let's cover all of them.

Community Itself

You can use the Freenode IRC channel, #libregamenight. There's a nice web-client available.

Individual Members

If you're an LGN member and don't mind getting a poke or something, put your contact info here. c:

Jaidyn - Sysadmin

You can see me on the #libregamenight channel under jadedctrl, email me at jadedctrl@teknik.io, or hit me up on XMPP with jadedim@kode.im'.
