tnyellowtomcat, I was told once before that if you DO NOT WANT your shares to be lent out, instruct your broker
OR
put a sell order in, all or none, good until cancelled, at some high sales price that would put them out of reach or at some price that you would not mind selling out and taking the profit.
Your broker may limit the 'GOOD UNTIL CANCELLED' timeframe to somethine reasonable (say 6 months), at which time it would be dropped (but I am not sure of this or not).
Maybe someone can clarify this for all.
