I hired an assistant several months ago and she has really proven herself to be an asset. Her professional background is much more extensive that the work I am giving her, and I'm ready to have her take on more responsibility. My question is, should I tell my clients about her before doing so? I would never give an assistant any work that involves my clients' finances, but I'd like to hand off some work to her that involves passwords - Constant Contact, Yahoo Groups, etc.

Any suggestions?
