#1 - Type in the code for the smilie you want in your sig. The code will display in your post reply draft when you click to imsert it in your message. Alternatively open up the [Get More]
window at the bottom of the Smilies box at left. That will give you the smilies with their codes. Just type in the code in your sig.
2# - Sorry. Can't help with the poll thing. It seems to be an issue with the board software. I have the same problem and have found that repeated clicking of the link that shows in the "Your session appears to be invalid" error message, sometimes 20 times, eventually works. Wish I could help you.
