Why is the email address marked with dots?
Because spammers use automatic bots to collect email addresses from web pages, the Google Groups web interface munges (hides partly) email addresses mentioned in messages so that the three characters to left of the @ character in the email address are changed to a link with three dots (…). Click the link and answer the question on the next page (it is called a CAPTCHA page) to unlock the email addresses mentioned on the message. In official Google discussion groups email addresses mentioned in messages are totally hidden so that they have been replaced with this text: [email address]. In official Google discussion groups you can’t unlock email addresses mentioned in messages. If you want to tell your email address in a message, you could try adding a space on left or right of the @ character or you could replace the @ character for example with (at), *, or some other way.
