Hi,
Ahhhhhh..... OK. I see now. I'm glad that my exponent will count as a
double check.
Thanks to everyone that answered!

You did not. If you complete the exponent it will serve as a valid
double-check. If you do not wish to complete the exponent I'll
bet someone on the list will be glad to take your Pnnnnnnn and
complete the test.

If Floris was using the automatic method as most people are, then he did
not connect to the Internet for a 60 day period. That is, after 28 days
the program will start trying to contact the server saying "I'm still
working
on Mnnnnnnn". The server won't release the exponent until 88 days after
testing began. This algorithm seems to work well as the recycle rate is
rather low.
There is a downside to increasing the 60 day period to a higher value.
If it takes longer to recycle exponents, there will be more "holes" and
the server will have to hand out larger exponents.
If Floris was using the manual method, then he neglected to use the
manual web pages to extend his assignment. The suggestion that the
manual web pages default to a value higher than 60 days is reasonable.
I'll contact the primenet guys to see if they can change it.
Best regards,
George
