If you want to make absolutely sure you reach me, you can typically find me online at my IRC network during most of the day and night.
You can connect to the IRC network via the following round-robin:
irc.k0nsl.org. There is SSL on port
6697. The network is also available over tor's hidden service at
wkv3h4s7kt2mtjfs.onion on port
If you don't actually have an IRC client installed locally there's still a way to reach me; you can use the webIRC client.
HexChat is my preferred choice of IRC client when it comes to GUI based ones. In all other cases, Irssi.
You can find a screenshot of HexChat, here.
