I find the best way to send PMs is with info in just the title/subject line, no text inside. Works
well if just sending an email address. Or send a couple of individual PMs continuing your message but only using the subject line, no text inside. I find that adding text inside the PM is usually a deal breaker and the PM will either not go, or will not be received. Usually I just send my email addy saying "Would u pls email me: xxxxxxx@yahoo.com. Thx!" (or however much you can fit in the subject line).
