  Dan's Finance: I took the NASD Series 2 and Series 65 tests got my Registered Investment Adviser license in PA (not too many have ever done this without the sponsorship of a company) and created a Stock Selection Seminar (and an Introduction to Stocks seminar) which I offered to teach for a nominal fee so that others could make money, too. I have retired and just manage money privately. If you are ever interested and in the area, I would be glad to do my seminar for you - for free! Just call 610-649-0750.
