Yeah, it has POP3 and forwarding if you wanted to use them, but I'm sure I saw a link/setting for using a simple view. Google pride themselves in their simplicity and power, and definitely had a version for cut-down browsers such as palmtops with little or no scripting... That'd surely work on Amiga browsers too...
*Edit* I just checked there, and there's a set of links down the bottom of the page for choosing your view. Among them is a "basic HTML view" link, so try that one on a PC if you need to, and then log in on the Amiga...
