FWIW, this would be my preference by far. I don't benefit from a 
constant reminder that I'm a patron (or subscriber, or whatever other 
term might be used). I'll get a reminder once every three months when I 
get charged and that's fine. I'm not going to forget anyway.

Also agree that if there must be something, whatever it is should be as 
visually unobtrusive as possible. Or at least, that would be my 
preference.
