New Incentive Site
I started out custom developing the site, but I don’t really have the time or the motivation for an involved development project (I think I already mentioned that). So in the end I did all the reasearch (now you don’t have to).
If you’re looking to establish an incentive/rewards site, it seems as though the best option out there is FSRevolution. A single site license is $199 and I’m looking at another $150 for template customization, so it’s not an inexpensive solution.
It was a bit of a bear to set up, as it has some specific hosting requirements to work, the main two being PEAR and IONCube.
PEAR stands for PHP Extension and Application Repository. I’m a Windows guy, so I have no idea what this is, but there’s a DB component from this repository that needs to be installed for FSRevolution to work.
IONCube is a encoder, used to secure scripts so people can’t deconstructing/steal it.
So if FSRevolution is a solution you’re looking at, speak with your host first to make sure you’ll be able to run it there.
After a few hours of back and forth with my host, and some advice for FSRevolution (who was very responsive), I got the site running. I haven’t yet had a chance to configure it, though I have taken a peek at the back end.
The site I’m running will offer points as rewards, with members being able to exchange earned points for Amazon gift certificates. Before I “go live” and start accepting registrations, I want to get a few things configured.
I want a person to get points for registering
I want members to be able to refer other people to sign up
I want members to earn a percentage of the points earned by any members they refered
I wasn’t able to get the above figured out after playing with the admin area a bit, and a search didn’t return anything, so I have a post in the FSRevolution forums.
I’ve already contacted an expereinced FSRevolution template designer, so a should be customized in a week or so.
Once it’s up and running, I’ll reveal the URl in case you’re interested in taking a peek, or even signing up, earning some points, and getting Amazon gift certificates!
