Google Groups is a free online community and discussion group service that offers the Web's most comprehensive archive of Usenet postings (more than a billion messages). I chose to use Google Groups as a means of communication as opposed to a forum because of it's functionality and ease of use. Google is the best thing to happen to the Internet since sliced bread. But don't take my word on it, take a look for yourself.
THELOUiSGUY' Math Google Group
Google Groups are the suggested means of communication when it comes to asking questions related to mathematics. Using google groups, as opposed to email, gives other people who may have the same question to see answers to questions that have already been asked. I have added a few questions that have been emailed to me in the past. If this helps even one person, then I have done my job.
