lol no im not sure what it means exactly.. I clicked on this because it reminded me of a camp i went to with friends and when we were siting around the fogo the older guys were giving people weird nicknames and they gave my friend Daniel the name "gaggles" lol :P
Yes. It is a school based e-mail that most schools have for students to use. It is very seguro adn most schools like it because the teachers can read every e-mail that a student sends or recieves. Also, it's easy to attach documents, which my school uses quite often. It's also a lot easier for teachers to e-mail students links for assignments or help websites.
