Since I am new here I would like to know a) How to add a smiley and b) what does " he/she is following you" mean? Thanks
We would suggest taking a look at the FAQ (frequently asked questions) page that you can find from a link on the main page after you log in or [agnostic.com]
If you "Follow" someone, that just means that you get a little alert when they post a new question or topic. The alerts show up in the top bar of each page.
