Billie, It looks like you may have changed some permissions and maybe your toolbar as well.
Try this: go to the top of any internet page.
If you're using Internet Explorer, go to Tools, then Toolbars and tell us what's been ticked.
If you're using Firefox, click on view, then toolbars and let us know what's ticked.
Have you got your smilies back yet?
If not... did you check to see if you have them enabled here on NeuroTalk. You can check that by looking under any message when you're typing. I took a picture of mine showing that option outlined in red (at the bottom). It should be unchecked.
See how you go and get back to us.
