So how about "We're putting together a conference..." or "Org name is putting together a..."? Even if you're the driver behind the conference, it just seems more charitable to use "we".
As kids we were taught by our parents to avoid I, me and my in letters we wrote to our grandparents. It was (is?) seen as rude. The justification wasn't about status at all, but rather about ego. The worst offense was beginning a letter with I. At least it was in German in the '70's. Anyway, the habit stuck but lately I find myself slipping.
I was never taught anything like that, but in one of my high school English classes all of our essays had to be written in the third person, so I get gain some experience doing it.
I actually put it to good use writing some email newsletters for a local conference where I tried to eliminate usage of I/we/etc because I felt that it was more professional.
