I can’t remember how to use .vmdx files. Please remind me. Please don’t tell me look in the Vassal documentation. I have and I can’t find it.
Download the extension you want to a known location. Launch VASSAL. Right-click the name of the module to which the extension corresponds and choose “Add Extension”, navigate to where you saved the extension, select it. Page 25 of the User’s Guide.
Thank you! I appreciate your help.
