Limit the number of characters in a textarea

[rmittal]

Hi,
In a textarea I want to limit the number of characters to be 368. After 369 characters the user shouls not be able to type. Also, the initial value in a textarea should be '**' and the user should start writing after these 2 characters. So then the characters the user can type will be 368+"**". How do i do this??
