Property Manager

I live in a condo association in Georgia and I am the secretary on the Board. The complex was built in 1973 and over the years a couple of managers embezzeled money so we are not as finacially secure as we'd like to be. I moved here in 2004 and the Property Manager was, and is, the Board President. (He was president first and the association elected to make him manager and pay him a salary because of the work he was doing for free). The current board is trying to deal with these issues. We feel it is a conflict to have the manager also be the president, but don't know how to tell him this because he is a great guy and works very hard here. He has tried to save the association money - because we didn't have it - by doing a lot of work himself, but we are doing better financially all of the time and we need to start hiring out landscapers, maintenance, etc. again. We are also trying to come up with a job description for the manager, so if anyone has one I'd love to see it! Finally, we have one member who has hijacked my email list of owners and is sending out complaints about every little thing and the last email was pretty much nothing but slander against the manager who she doesn't like. I have asked her to cease and desist - with no response. Please help with any suggestions!
