This might be a little too complex for here but I thought i'd give it a shot. Basically, I'm going to have a members-only WordPress powered site and in order to become a member there is a fee and in order to pay the fee you must pay through ClickBank. From here I need ClickBank to e-mail the registration URL to the new user. What I was really wondering was if there was a way to make the URL for registration randomized instead of www.site.com/blog/wp-register something like www.site.com/blog/er3938483rfidjfsnf or something like that (or if there is a way to do it with browser cookies?). The reason I would like to do it this way is to prevent non-paid members from signing up for free. I have seen this done on a different membership site so I know that it IS possible somehow. The only other option would be manually adding users which is not feasible once I have a high volume of new members. I hope I explained this clearly! Any help would be greatly greatly appreciated and if necessary I will pay. If you need any more info let me know!
I'm guessing you have to use PHP to create a random "url" and then have the appropriate post/page entry into the MySQL db. Maybe you can get more help at Wordpress' forums.
