This isn't really for the developers of this plugin — because I know you're very busy, too add every single gateway available — but more for anyone who has been able to add a new gateway to the plugin.
I'm looking to add CardSave via their redirect / hosted method;
which from what I can see, should be similar to what eShop does with current gateways; shopping cart on WordPress site - then sends request for payment to gateway and waits for a return saying payment was OK or not.
Does anyone have any experience or tips to share please?!
