I really think this is a terrific idea. But I am not the one to do it for two reasons, first I already have a long "to-do" list; but more importantly, it should be someone who likes to spend time thinking about how much work would be required to complete a proof. The list would have to balance the most interesting numbers with the most reachable numbers. (If the primes on the ten most wanted are impossible, then what would the list be worth). BUT if anyone would like to make such a list, I'd be glad to give it a home OR would be glad to link to it where it is (a PrimeForm directory?). It would be nice to have a top ten (or so), plus a link to a page which provides a way for others to post ones they'd like to see proven with a short note (why, or hints how to proceed) Chris C.
