Resume – work history, exaggeration and ethics

As I’m working through my resume re-write mapping my work experience to the web strategy competencies, I’m trying to be careful how I state my role in the events/projects/initiatives I reference.  I want to avoid exaggerating my work.  Not sure if it stems from my personal standard of ethics or because I’m under-valuing the work I did. Either way, I don’t plan to join the 30% or so of people who over-exaggerate on their resume.

So to keep my ego in check (or to boost it), I’m IM-ing friends and former co-workers to get their perspectives.  Not sure if there is a better way to approach this — it makes the whole process much more time consuming.
