Another reason to use e-mail (and we're talking about e-mailing via FlyerTalk here, which some responders may or may not have understood) is that a lot of us have access to e-mail even when we don't have access to the Web.

For instance, I can retrieve my e-mail messages via phone. (Sometimes the computer voice makes it difficult to understand them -- especially the ones for V1@gr@ from [email protected] -- but it's a handy feature nevertheless.) But I cannot get PMs via phone. (I can also get SOME posts via e-mail -- if I've subscribed to a thread -- and therefore by phone.)
