When I was a newbie, I didn't realize that CAPITAL LETTERS were the aequivalent to shouting. I simply realized them as means of stressing something, like putting stars around a word, like *this way* .
Actually I still use capitals to stress words or parts of a sentance.
Especially smilesy - I don't know any Novel that incorporates smileys. <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
Except for some fanfiction, yes, I haven't seen smilies in novels <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />.
