I am currently in the need of a probably simple modification for a script. The site is at http://www.archbattle.com and there are referral links on the site, when a user signs up under the referral they gaining (20 Citizens), this has became abused where users just create multiple accounts under the links, and is physically impossible for me to check over 500+ member accounts. So I need something added onto the registration not allowing the same IP address to register multiple accounts or people using the same passwords etc. Please post here with a quote or PM me with one. My budget is pretty small for this. Regards, Carsen K.
