Well right, but the sent messages won't have a "return number" of my normal SMS phone number for the recipient to reply tol they'll go to my gmail inbox instead and show up as emails.
What I really want is a totally transparent way to text from a PC. When the recipient gets the message, it looks like it came from my phone. When they reply, it's delivered to my phone (as well as to the web-based chat).
Thank you though! Maybe I can make it work.
