Been a couple of days since I said I would release an update on the status of the marketplace.
Thank you to everyone who has given feedback. If you have not visited the site recently I recommend taking a look at it . The colors have changed to match the solar2d website, subscriptions have been added, new plugins have been added and will continue to be added, a plugin submission system(which I have been using to submit my plugins) has been added (see photo below), subscriptions have been added, payments have been testing and working, and I am also happy to announce that I am now taking applications to be a plugin vendor for the solar2d marketplace!
While some vendor features are still in development a lot of features are done (like plugin activation analytics, parts of the vendor dashboard, submission page, etc). You submit your plugins for free, paid plugins, or even subscriptions based plugin. For paid plugins and subscriptions based plugins I take only 15% percent for handling plugin hosting and payment processing fees for your plugin.
To sign up to be a vendor create an account and sign in, go to the account page, and click the apply to be a vendor button.
