I posted an idea about mail in Controlling the inbox, which is not Notes specific, but as we use Notes for email in EY I pinged Ed Brill (a prominent IBM blogger, amongst other things I'm sure - but that's how I know him) with the idea and he suggested putting the idea on IdeaJam.
I've been to the ideajam site before as Ed has mentioned it on his blog in the past, but this was my first use of it. It is absolutely brilliant. Almost every feature I have thought of is already there. The interface is clean and simple.
I want this inside EY to promote innovation.
