Well, if people would stick to PrimeNet assignments, this sort of 
thing wouldn't happen...

At least the other "culprit" is bothering to report the results, and 
the duplicated effort isn't too much - only about one quarter of your 
investment.

BTW would anyone who has run P-1 on exponents in the range 100000 to 
125000 (prime, with no known factors) without reporting the limits 
used please report them to me. I'm working through them with B1=1E6, 
B2=25E6 but seem not to be finding any factors - possibly someone has 
done them before?
