I'm actually member "RSJ". I haven't been around in a while... but I have always appreciated this forum's help. It seems that access to my e-mail that I used to register a few years ago is locked

I hope I am not violating any rules; I have sent a PM to site admins in the hopes of getting this fixed. Anyways, on to the bigger problem.
I am coming up on my first renewal. From my understanding, despite what I was told in my class in 2010, the process has greatly changed.
Anyways, I am moving.... in fact I have keys to both houses and am ready to "pull the trigger" on the move whenever. I called the DPS number and eventually got through to a represenative who said, "use your current address, then hand write the new address onto the paper that you'll print". Well, I followed her instructions, paid the $72, checked the affidavit boxes, and went to print. All that printed was a "checklist" that has two boxes: (1) Checklist, (2) TxDPS will attempt to nofity me if my prior prints or pictures are no-good.
So my question is, (1) how and where do I "write" in a address? What is this https://www.txdps.state.tx.us/InternetF ... CHL-77.pdf Do I send this in too? (2) what am I supposed to send to them (is it really just this checklist that is self-checking???) and (3) When can/should I update my Driver's license?
Thanks,
I hope this is clear... if not I can elaborate.
