Setting yourself up for all kinds of annoyance posting your number up like that mate. You could have said "If anyone has a spare ticket give me a shout on here" and then exchange numbers lol? I was let down by somebody for Arsenal tickets, had arranged the spot to meet them, even received a text that morning but after 1pm his phone was off. Texted him telling him he was lucky I didn't know what he looked like lol
NI Saint is right, I suggest you edit out your number and change the message to "PM me" or words to that effect. Good luck anyway.
No phone numbers is probably a good idea...check out here - http://www.not606.com/showthread.php/188838-Villa-Away-Pre-Match-Pint
