I've just added nice integration of github and Travis CI.
In a nutshell, everything happening on our github repository (issue created/commented/closed, PRs, commits, CI build) will be notified in our ironjacamar room.
A nice way to don't miss anything happening on the project.
I'll have a look if it's possible to add also notification from google groups, I've not found anything working out of the box, but I'll look better when I'll have 5 mins of spare time ;)
As usual any opinion, contribution or suggestion are more than welcome
regards
S.
