Question about EE

So I have a question about EE servers…Several really…

Can one update a module to EE specs basically? Are modules updatable so you do not need to redo it all?

Can other players join the module if they have 1.69 (diamond) instead of EE?

Anyone still using 1.69 cannot connect to an EE server as the version numbers are different.

A 1.69 module can be loaded into the EE toolset, but once saved in the EE toolset, will require EE to run, as again, it gets saved as a newer version number that EE is currently on.

FP!

Thank you so much for this!!!
