A cool new feature is now available at #firstname.lastname@example.org (Yes, Marc, that is where all the hip children hang :-P):
If in a conversation a string "issue <number>" or "#i<number>" or "<URL of an issue>" appear, IZbot, a dedicated bot, completes the information with the URL, number of the issue, its nature and subject line (whichever was missing in the conversation). This is saving time looking up the IssueZilla while discussing about issues. Whoever implemented it, big thank you!
Update: The thanks go to Christian Lohmaier, aka cloph. Danke!!!
