Hi everyone! Just joined this community today thanks to @Scrummando. I'm David, one of the co-founders at Retrium (previously mentioned in this thread, thanks @andybacon and others!).
Glad a few of you have tried (and liked) Retrium for your distributed retrospectives. A few months ago we launched Lean Coffee as a technique, so you might want to check that out too.
Anyway, this is just a friendly "hello". Nice to see some familiar faces here and can't wait to get involved in the discussion.
