You could export your user module, edit the resulting text file, change the user information using a text editor like notepad, and then bring it back into Swordsearcher using Forge.
Export using Swordsearcher menus -> User menu/advanced user module maintenance/export for Forge.
Download a copy of Forge here: https://www.swordsearcher.com/forge/index.html
Swordsearcher will make a backup copy when you run Forge, but you might want to make another in case something gets messed up while experimenting with it.
Play around with Forge. It useful especially if you need to change a lot of topics in a module (i.e. adding a link in each topic to go to the table of contents).
