AN came out with a new app 10^20 and most people moved over to it since you can actually find Amicable pairs.

The admin wants to finish the original search (no more pairs available) so he has "doubled" the credits/WU. This is for CPU only, GPUs will automatically be given the new app.

If you are wanting credits on AN, and don't care about how many pairs you find, then this is a great opportunity to run up your score
