The problem seems to affect
Internet Explorer 6.0 users, using Windows XP without the Service Pack
2.
If this is you, the simplest way to correct it is to go to "Edit Profile' (in the upper right hand
corner next to your
name, after you've logged in) and under the "Site Options" tab there is
the option
for "Content Editor". Click on the drop down menu and select "Plain
Text." That should allow you to post, but you can't use smileys or HTML
with it.
Other than that, the solutions are
Download Internet Explorer 7
Update XP with the Service Pack 2
use a different browser
altogether.
Thanks for your patience, and I apologize for the inconvenience. Hopefully, we'll have a better solution soon.
