I mentioned it initially but went back and removed it. I couldn't decide if the stating the project specifically was relevant or not. I often over analyze what I'm posting here for some reason.

It was Pidgin, but back when it was called gaim. The pidgin transition occurred while I was leaving. I stuck around long enough to participate in deciding on the new name / logo / branding and then handed everything over to Sean officially.

Oh wow. I've used your work almost every day for many years now. Thank you.

You are very much welcome. People like you are the reason that I stuck with it for as long as I did.

I think adding details like that makes your point more strongly -- too many folk on the internet shoot their mouth off with vague claims, which when poked at completely fall apart. But in this case it only took clicking on your user profile to see that yes, the project you were referring to really was a pretty popular one. :)
