sure can. PMs are for your personal use. Just like e-mail.
just make sure you PM the person that originally contributed it. Thats why we dont take the whole posting out during the edit, so you PM the person at your discretion. If we wanted to censor the whole thing would be gone, frame person an all. unfortunatly, you'll probly noticed the big words BANNED on some postings. You simply cant PM them...they are no longer part of the forum PM network.
We only take the items off that are against the forum policies that are open, like the posts. see, we aint such bad guys.
