will all of the current games on my server be OK if i upgrade from 3.11.55 to the current version?

I would back everything up first .. make TWA files of each edit.

Then put them on cd for later use .
Go ahead and do new install and set codes up.
Import your games and check the global settings to make sure
they are what you want.

One Tedit setting to look into is on option screen H
(zero) Interactive sub-prompts .. default in new twgs is off.
But I remember old players knew it to always be on.
This is where you could hide on a port and get fig kill messages
and chat with your corpies.

But by defaulting it to OFF , means this is not avalible.
This is the only other setting I recall that you may
need to look out for.
All other stuff .. should work without problems.

thx for the advice vid. i got tired of waiting for replies so i just upgraded it recklessly. all games are working fine.
