Hi everyone.
Working on a project soon to be released and we will need two things:

1.to implement a form on our sight to automatic sign up and cancel for our newletter
2. an editor to make eyecatching newsletter

My webhost offer a code to implement on our sight that automatically adds new recipients( or cancel ), BUT doesn´t have a newsletter editor to go with this service, thus leaving us with a good and automated service but with no good design at all(just text)!

So, Can anyone help in suggesting how to go about this? Please if anyone know of a great editor, tell me please! Also, if so, HOW do I somehow implement a code on the sight for automatic signup that magically transfer those new members into a perfect memberlist into the editor program! I hope you get what I´m after.
Most gratefully,
