Floyd you really must have too much time really...Please contact you friend Mark, he already has his paypal back. And please don´t tell any further bullshit. After Mark had returned my paypal, your friend Mark tells me via email that he wants cash in a letter, then you send a pm on here telling me "No, send a paypal don`t send cash"... Mark then again via email wants a normal paypal, you talk again about a return...my oh my.. This would already have been sorted if you would have talked more to your friend Mark then with me.
Idea for the future: Get your own paypal account.
And get out more.
Marc
