I think that having the competition only open to subscribers is also a good idea as well. Just another benefit of being a member and a little incentive not to misbehave.
I disagree with the 'Subscriber only' option. I am not a subscriber, and the reason for this is because I do not have a PayPal account to become one. I have offered to post a cheque to Adam or Slateman, and I offered to do a direct debit to either, and the offer was refused as, to avoid confusion, and given the large membership, it wasn't convenient.
I don't have PayPal as the company messed up my account in the past and caused no end of confusion fixing it up, not to mention the inconvenience and I don't wish to open another PayPal account and have this happen again.
So why, when I have been an active member for a long period of time, with no infractions ever issued against me, yet a large post count to show I do contribute, and have shown a desire to become a subscriber, should I not be allowed to enter this competition ?
<insert fine print here:> Of course, all of the above is hypothetical, as, like Sdaji has expressed, after having been placed in the last snake comp from Southern X Reptiles, I have a few personal/moral/ethic issues about it being fair to enter this one.
