Ok , good question .. this is what I do :

1) I'de make a database with Swath called SysOp
make it 30k .. just so its good on any edit.
2) make a Twx databae with same name also 30k

Regardless of actual game size.
These 2 acounts are your admin tool on your server.
You never save the Swath one after you first make it.

3) Set both up to point to admin port of your server , and the twx to address localhost (your server)
Use your SysOp name and password
no game letter.

4)Use twx script 14_Login.ts (may need a bit of editing)

5) Use of the new portfixer ...
yes , you have to log in through the admin port to Tedit of chosen game before you run it.

I hope that answers your question.
