Hi,I think there was some URL toaccess Gmail in HTML only, but I can't find it. I found one complicated. Is there any short url to access Gmail in HTML?. Thanks.

Maybe this one:
http://mail.google.com/mail/h/

(There's also http://m.gmail.com for the mobile version.)

This seems to work:
mail.google.com/mail/?ui=html&zy=f

How to find other HTML versions in the future? Disable JavaScript and enter the normal URL.
