Hellgate: London and you are available at 7pm EST today, then fire up your favorite IRC client and get ready to talk to Flagship Studios. Their last developer chat was pretty candid, so if you are still playing HGL or have renewed interest since the release of Stonehenge, participating in this chat may be fun and informative.
Here are the details:
For questions during the event, type /msg DevBot yourquestionhere where "yourquestionhere" is your actual question. There will also be a separate channel just for chatting with other attendees.
I use Trillian for IRC, but mIRC is another good one. For The Gamers is also providing a web-based client for the chat. Full details on how to connect if you are having issues are provided here.
Maybe I'll see you there, preschooler permitting.
