New devs are always welcome! It’s not that important if you’re not experienced in RakNet or networking, if you have the willing, you can do this! Check out https://github.com/jaller200/LUNIServerProject/wiki/Getting-Started-in-Development for some additional infos and feel free to download and play around with the source.
As long as you hope, you can.
P.S: Did you already join our Skype community chat? If not, add julistein02 or HappyAngryCatfish to come in there.
