MUD crashes and clones

[Yase]

When the MUD has big crashes like this, someone informed of of a clone they were playing at wodan.servebeer.com But I either couldn't get on it or didn't know how to do it not being very familiar with computer type languages. What's this clone and how can I use it?

I'm not certain, but I think it's just for creators and playtesters to mess around with new code before adding it to the mud.
