I like the revised (#8) better. Can we make the square look more like a sheet of paper -- well not just like a sheet of paper, but reminiscent of a sheet of paper. The logo is almost telling me that we're collecting lots of little sheets of paper and making sense out of them all -- which is kind of what we do.
Certainly in the lead, now the interesting question... I know I said white (no) background, and we need that. But we're also going to need it to work on the new website (now live at www.irbmanager.com). We're thinking some sort of oval-y background for the site, or with it inverted or something. Helpful, no? :-)
