Hi there!
Me and my friend are big fans of the roller coaster tycoon series and have recently gotten into rct2 and thus, found rct2 Open! We have always dreamed about playing multiplayer and building parks together, and we found out now that this is actually possible! I made my own server, making it private and setting it up with a password and name was easy - however, my friend has found the server, but he cannot join it as there seems to be a dark red circle next to the name. If he clicks on my server, a message pops up saying that it is 'unable to join'... any suggestions/solutions?
