Technius Yes it can? Get the players name, if it's already a player logged in, then kick this new player?
@Technius No, because if the connecting player join a bit in the server, or something try join in server, the player that already playing "lock". Can not break blocks, talk or use commands.[/quote]
Can you read the OP before posting? Thanks. I was pretty sure that the joining player kicks the user that is already online. Happened to some servers I played on a couple of times. I didn't notice they were on offline mode, until it happened. But no, it is not possible, as I believe I've seen someone post something like this: And it may not work as intended if you try to have something like this. I suggest having your offline players buy the game, and making your server on online mode. Oh, and could you word your posts a bit better? Hard to understand.
