Ok, suppose you can run a marathon. Now, run 2600 miles, ok?
What? it is only two digits more!

Yes, testing 10-digit exponents is not implemented. If you really, really want it, write your own program. It is not hard, it is only two digits more. :)

What? it is only two digits more!

Yes, but Prime95 can test 6-digit exponents, too! :-)
And then of course it can test 8-digit exponents.
It can even test some 9-digit exponents. But not 10. And then again, if it did, the owner of the computer wouldn't be around when it finishes. Heck, the whole city (and maybe the continent) wouldn't be around.

Just set up the "Test=" line in your worktodo file, without a key, then do a manual communication with the server.

First, use this page: http://www.mersenne.org/report_exponent/ to check if the number that you have selected is already assigned to someone else.

If you are looking to set a record, win part of the prize, and make history, you will have to get a number above 332192831. The first available is 332194529 (Someone else tested that number before and it did not appear to be prime.), 332216971 has yet to have a primality test on it.
