Purchase WSN Links
Friendly to tight budgets.
The Lite version has these switches disabled on the Admin Panel -> Settings -> Switches page: Sponsorship, Shopping Cart, Send Payments to Submitter and Affiliate Links. Lite versions are also a lower priority in the support queue.
Standard licenses allow running one copy of WSN per license.
A domain license allows unlimited copies under a domain name.
e.g. http://site.com/, http://site.com/dir1/, http://sub.site.com, etc.
