I've heard two schools of thought when it comes to "designations" (such as SRES). Some say they are plain meaningless to most people and therefore will not help plus it's a waste of your time. Others say this can be a huge boost to your career, especially for people looking at agents online and/or seeking out agents by their designations. If some are worth it and some aren't, which are the designations to go with? What's the scoop?
