They appear to be turned on, I entered mine in. The check boxes are all checked. And yet, no sigs?
probably disabled.
Disabled.
How come?
a few reasons i can think of....
if you check out the rules, you will see that posting your email address is not allowed, many people in their sigs have their email in there.
also, these are tech forums (with the exception of the off topic setion) therefor, sigs are not needed and would just clutter up threads -- making searches more difficult.
