Messaging

How can I send a text message to someone using their phone number? When I try to enter a contact, it demands an email address, which I don't have. Thanks for any help.

If you know what network they are on, you can usually use that networks email to text gateway. For instance, Verizon's is vzwtext.com.. you would mail <number>@vzwtext.com and it would text them, when they respond back it would email you back.
