OK, so just got a
call at work from a nice lady at the DPS office.
Seems that the missing signature sent back as a
faxed document was not acceptable 
and they supposedly tried to call me back and tell me that.
However, they were most happy that the MAILED DOCUMENT just showed up, so they called me to let me know that they had it, and everything was kosher, and
"You should get your license in just a few weeks."
Waiting is not so bad. However, knowing that they have all the paperwork and I have a greenlight is a big relief!
