We have to accept that this is never going to be exactly like the old server but I am slowly learning how to alter things and eventually will get it as close as possible. I have altered the jump speed so that should be better. The first jump is the highest and if you keep jumping it reduces. This is due to energy reducing and is normal for this mod. I actually like this feature but haven't yet found out how to alter it.
I am checking re undermap in Arbo. I can see that it can be done but can you kill from there?
I am going to have lessons on map adjustment so that I can stop access to places or send back to respawn etc.
Thanks all of you for the input. Will try to follow all advises received.
Yesterday I have told Redgun and Dilly about the new server - they've tried to join the new server right away.
But the result was the same as mine - both have received the KEY CODE IN USE message.
