You can find regular expression primers all over the internet, but to answer these specific questions: [...] means any of the characters in the range; the $ means "end of string"; and {2,30} means at least two, and at most thirty, of the preceding character. So you have to have one from the first group, then 2-30 from the second, for a total of 3-31 characters in your names. ChrisA -- http://mail.python.org/mailman/listinfo/python-list
