Why, why, why!
I was just registering and logging in to www.dpreview.com to post a message.
Just so you know, I think it's a great site if you like photography or want to learn more so I don't want to bash them. But, I had a bit of an issue.
I was creating a login account and entered my email address. firstname.lastname@example.org.
Got an error message: can't use an Internet email account.
In this age, where most people's email IS web based because ISPs change so often, why would ANY website not allow you to use an Internet email account? That's what most people use.
