I have created

I have created a multisite with the hope of using ProSites to manage it but it does not have any payment gateways for my country. I have requested on numerous occasions for Braintree to be implemented but alas ...nothing. I now had a look in the files and see 2checkout is in there but is not an option in the wpadmin.

Does this work or why is it not enabled as I can at least use this gateway in my country?
