Re: Polroots/mod suggestion


Thanks for that -- his comments had seemed completely stupid to me,

Strangely enough, gmail put this email of yours into spam (but not

After that he popped his head up on one of the prime number related lists I help moderate, and his gibbering of nonsense caused a swift always-moderated flag to appear next to his name there too.
