Storing it on a db. And every time a user submits an entry you go thru your db to see if this ip address has made a submission in the past.

Gotta get this done.... You could do an email confirmation thing.. IE the "sweepstakes" emails the person, & if they click on the link - its confirmed. However, it doesnt preventpeople from having multiple email addresses. -- G NZ community groups - [EMAIL PROTECTED] com NZ-Website space offered. <!-- #ygrp-mlmsg {font-size:13px; font-family: arial,helvetica, clean,sans- serif;} #ygrp-mlmsg table {font-size:inherit; font:100% ;} #ygrp-mlmsg select, input, textarea {font:99% arial,helvetica, clean,sans- serif;} #ygrp-mlmsg pre, code {font:115% monospace;} #ygrp-mlmsg * {line-height: 1.22em;} #ygrp-text{ font-family: Georgia; } #ygrp-text p{ margin:0 0 1em 0; } #ygrp-tpmsgs{ font-family: Arial; clear:both; } #ygrp-vitnav{ padding-top: 10px; font-family: Verdana; font-size:77% ; margin:0; } #ygrp-vitnav a{ padding:0 1px; } #ygrp-actbar{ clear:both; margin:25px 0; white-space: nowrap; color:#666; text-align:right; } #ygrp-actbar .left{ float:left; white-space: nowrap; } .bld{font-weight: bold;} #ygrp-grft{ font-family: Verdana; font-size:77% ; padding:15px 0; } #ygrp-ft{ font-family: verdana; font-size:77% ; border-top:1px solid #666; padding:5px 0; } #ygrp-mlmsg #logo{ padding-bottom: 10px; } #ygrp-vital{ background-color: #e0ecee; margin-bottom: 20px; padding:2px 0 8px 8px; } #ygrp-vital #vithd{ font-size:77% ; font-family: Verdana; font-weight: bold; color:#333; text-transform: uppercase; } #ygrp-vital ul{ padding:0; margin:2px 0; } #ygrp-vital ul li{ list-style-type: none; clear:both; border:1px solid #e0ecee; } #ygrp-vital ul li .ct{ font-weight: bold; color:#ff7900; float:right; width:2em; text-align:right; padding-right: .5em; } #ygrp-vital ul li .cat{ font-weight: bold; } #ygrp-vital a { text-decoration: none; } #ygrp-vital a:hover{ text-decoration: underline; } #ygrp-sponsor #hd{ color:#999; font-size:77% ; } #ygrp-sponsor #ov{ padding:6px 13px; background-color: #e0ecee; margin-bottom: 20px; } #ygrp-sponsor #ov ul{ padding:0 0 0 8px; margin:0; } #ygrp-sponsor #ov li{ list-style-type: square; padding:6px 0; font-size:77% ; } #ygrp-sponsor #ov li a{ text-decoration: none; font-size:130% ; } #ygrp-sponsor #nc { background-color: #eee; margin-bottom: 20px; padding:0 8px; } #ygrp-sponsor .ad{ padding:8px 0; } #ygrp-sponsor .ad #hd1{ font-family: Arial; font-weight: bold; color:#628c2a; font-size:100% ; line-height: 122%; } #ygrp-sponsor .ad a{ text-decoration: none; } #ygrp-sponsor .ad a:hover{ text-decoration: underline; } #ygrp-sponsor .ad p{ margin:0; } o {font-size:0; } .MsoNormal { margin:0 0 0 0; } #ygrp-text tt{ font-size:120% ; } blockquote{margin: 0 0 0 4px;} .replbq {margin:4;} --> [Non-text portions of this message have been removed] _______________________________________________________ Novidade no Yahoo!
