You can think of PopLava as being a company or a software developement studio. PopLava aims to build creative and exciting software. The owner (tsfreaks) is trying to build PopLava into something bigger and better.
The "Resource Center" is an online store where you can quickly buy and/or sell code, art, and other assets.
The store was built by PopLava using BYOND as the platform. By using BYOND, the store is tightly integrated with BYOND member services and provides users with additional security and familiarity.
PopLava's goal for the store is to increase the productivity of BYOND developers while also giving incentives for people to constantly contribute. I firmly believe that if the store picks up momentum, a ying/yang effect will take over and drive the store to success. PopLava will commit to adding features and improving the whole process while contributors fill up the catalog.
In my book, this is a win/win for all those involved.
