We have a number of upgrades that need to be installed on CS Cart Multivendor. All of them are available, except for one that will be rolled out in the next week or so. They shouldn't be too intensive, though we are looking for someone who understands the program to ensure they get installed correctly without any conflicts or issues.
You can find a list of the current upgrades attached. We are hoping to find someone who can continue to work with us as we develop the site and provide technical support on an as needed basis.
