We say it all the time, but now you can lose out if you don't have prime reporting enabled.
SGS primes are currently only on the T5K list for a few days before falling off the list. If you do not have prime reporting enabled, there may be no time to contact you before it's too late to report your prime. Rather than let the prime go unreported, we will report SGS primes under the DCer's name if you don't have prime reporting enabled. If the DCer also doesn't have prime reporting enabled, we will report the prime anonymously. The alternative is that the prime doesn't get reported at all.
For more details and discussion please see the 4888 thread in our Sophie Germain Prime Search topic.
To enable prime reporting, please go to "Your account" on the menu on the left, then select "PrimeGrid Preferences". Scroll down a bit to where it says "Primary (default) preferences:" and select "Edit PrimeGrid Preferences".
Scroll down to "Reporting primes to the Prime Pages" and click the two checkboxes for granting permission to report primes and to send you an email when a prime is found. You must enter your real name. T5K will not accept fake names or user names. Please enter your name as "given-name surname". (Note that even in cultures where the surname is normally put first, we need the given name first and the surname last.)
If for any reason you don't want us to use your name, we can report anonymously for you -- just check the permission box and enter something like "report anonymously" in the name box.
Finally, scroll down to the bottom and click on the "Update preferences" button.
Please do not PM me with support questions. They will usually go unanswered. Ask on the forums instead. Thank you!
