Hi.
Can't really find anything like that. Basically, the idea is to have a chat command or GUI where you can select a Steam friend (maybe similar to sleeping bag-ins) and add him/her to friend invite on that server. When the friend accepts it, both get a set amount of reward. In my case, it would be the coins for Economics plugin. Of course with the config json where we could edit the reward amount received and messages.
Ideally, maybe it is possible to use Friends API with Steam so friends can send a Steam message to connect to the server and message of reward.
Obviously, the server should store a data json with information on which steam IDs already have a mutually redeemed invite reward.
Shouldn't be very complicated for an experienced plugin dev.
P.S. I can't afford paid development right now.
