Taking possession of your shares certificates is one way to make sure a shorter doesn't borrow them, as is converting all accounts back to non-margin. Neither tactic stops naked shorters, though, who don't "borrow" shares in the first place (nice euphemism- "borrow"). I much prefer the dividend idea! Maybe starting at about say 2 cents a share?
The dollar is "strong" only in comparison to other weak currencies, and in the sense that it is the place to put your money when you pull it out of stocks (as is gold, to a lesser extent). Lots of cash still waiting on the sidelines.
