I've been a shareholder for almost 8 years, a year before they split the "old" FNB into FNB and FLB. And then FLB got bought by Fifth Third.
I've participated in a DRIP, and also used to buy and sell lots of 400 shares. Buying and selling was bringing more money than DRIP, where we just broke even (although we were at the same point several times before). We just decided to let it run and let the power of compounding do the majic. I still expect them to raise the dividend, maybe even to old 18 cents/Qtr.
