I've gone ahead and set up a Discord server so that anyone can have a well moderated general place to chat live about Astro or Tezuka. I know my old IRC method never quite caught on in here but as Discord is quickly becoming the new IRC, Skype and Teamspeak all in one, and works flawlessly in a web browser, I have hopes that this should hopefully catch on.
You can get an invite from this link, or the following URL:
