& Go to RSwebclients.com and create an account.
Install hamachi.
Make sure you have WINRAR. Extract your source to your desktop. then you will see a folder on your desktop. thats a good thing.
Go to hamachi and click Network.. or create a network. Type in your network ID.. Which would be merchscape or something.. then a password. ..Good.. click on that and at the top of hamachi you will see your network ip and all that exciting stuff.
Go to rswebclients.com and sign in to your account, click 'create a client.' ..Type in your network ip that hamachi tells you.. and all that other stuff. For 'client list' .. it will be ErasedPKz..
I can't really explain about running it..
but keep the links it gives you on the website once you create it..
in the folder on your desktop click around and double click 'run'.. it took me a few seconds to find mine...
then copy/paste the first link on the website into a tab and it should start loading..
but when you first join.. teleport home.. you only need to do that once just to get things started..
I know this isnt great.. and im pretty sure people playing need to have hamachi too in order to play your server (i may be wrong) i didnt read that part.. it didnt say that but you never know..
I'll try and find something better so that it is easier to go to.. but in the mean time, you could try this and play it until you can get something better up :S..
Im not sure about item coding and promotions.. you'll probably know immediately since you will be the creator of it.
