Already had 2 spam attacks, one was from a registered user, the 2nd one was not. I figure I can cut out half the spam by requiring registration. The 2nd one it seems was by an automated program that had cracked the captcha algorithm I IP banned them but is there any opposition to registering. UPDATE-- There are 2 very persistent spammers going on right now, they have slowed and I have blocked a majority of the IP Addresses they are posting from but a couple have still slipped through.
