The egrep is using a leading anchor (^) to make sure the grep matches the beginning of the line. If not, and the group pattern matched as one of the users it would print those lines too .. which is probably undesirable.
Grep understands the '^', so egrep is not needed. Typically, you only need egrep for patterns that involve alternative re's, like looking for one of "abc|def|ghi" which grep does not recognize.
Also, it might be helpful to trim your replies so we don't need to wade through the whole thread to see your reply.
