What I like about this: 1) no globe. 2) the "international conference" aspect has more emphasis than the IEA aspect... making a logo for the conference... and not for the organaization
What I don't like: 1) The IEA does not read well. All I really see is EA.
Since you have IEA in the regular text... simply replacing the graphical IEA bug with art that somehow says "reno" (along the lines of what is going on in #37 would make this a lot stronger for our needs.
I can read IEA in these... but now that it is readable, it takes over. We are branding the INTERNATIONAL CONFERENCE, not IEA. If you drop the IEA and replace it with some graphic that says "Reno" (check contest feedback for some reference), or that indicates some other aspect (networking, success. learning...) of a conference, it will be better.
