Even if pool users check this "auto-select" option, they are still going to complain when their GRC income suddenly drops to zero when they get automatically switched from PPS Sieve to GFN subproject.

This GTX1080 user is a good example - he is getting around 6.5 credits/sec crunching PPS Sieve, but only around 2.1 credits per sec running GFN20. For shorter workunits, like GFN-15 of GFN-16 (which are most likely to quickly reveal a new prime), he would get much less than that, basically all his mag would disappear. Other prime-discovering subprojects are all CPU, meaning they earn even less GRC, since GPU crunchers collect most of the credits.

The PrimeGrid's idea is that users who get a chance to discover a new prime don't need large credits, because they are always honored as prime discoverers, listed on PrimeGrid's webpage and on The Prime Pages. This credit restriction severely limits their GRC income in turn.

We could turn the tide by:

1. Rewarding every Gridcoin user who discovers a new prime (either from the Foundation or through donations).
2. If a user discovers a new prime when crunching in grcpool, it would be very beneficial if we could reward him individually. That way, he would actually be motivated to check that "auto-select" option because he would know that both the reward and recognition are coming his way, if he discovers a new prime.
