They are available here in our Smilies column (to your left when you go to reply to a post. If you have an anti-pop-up program in your computer, just hit control then click where it says get more, and there they are. Copy and paste or type in the symbols
and they appear.
There are also independent websites where you can get them- Best Smileys is one, Christy has a website she uses with great smilies, maybe she will cough up the address- http://bestsmileys.com/
That is the one I use-
Hope this helps
