The size of the username box in this forum is too short to see my full email address and as a result I often have to try a few times because I cant see if I make a typo. This is rather annoying because you can see if you perhaps made the mistake in the password because all you see is a row of dots.
Is there any way I can use a shortened username? I seem to remember I entered one originally but it has never worked
This is a great question for Adobe Tech Support.
The only solution I can think of is to create a whole new Adobe account with a shorter name.
There is a good, active forum for Forum Comments. Adobe-Admin (John), can help you with all sorts of issues with Log-in, and accessing the forums. I would post there with the issues and your needs, and wait a bit for John to get to the post. He's good, fairly quick, and works hard to help - but he IS overworked, so you may have to be patient.
