I registered for three services without much difficulty. It was not possible to register for NetAddress without graphics because this site does not have text labels for graphical buttons. All four sites are technically accessible once you've registered, but all four lead you through a maze of links before you reach e-mail. It took about three hours per site to develop a strategy for logging on and quickly accessing my mail using a screen reader. Inexperienced users will need even more time.
Browsers vary greatly in their ability to work with assistive technology devices.
For example, as a screen-reader user I use browsers that offer full keyboard support for commands. Someone else may need a browser with flexibility in fonts and character sizes. Some Web mail sites provide best security support when using Netscape. Some make such extensive use of frames that they do not work well with Lynx. It is the intent of Web mail providers to change how we interact with e-mail and the Web so that our access to the Internet will become as mobile and as flexible as we are.
