Hi Teus, I deleted my initial message in order to do some more research on my options, but I'm thankful for this reply.
I had not seen there was a desktop version until yesterday morning, and since I don't need a collaborative environment, I'm wondering if that would work for me. I'm thinking I could Remote Desktop from my Mac to my Windows machine for this, which I'm much more experienced with than doing a Linux install. I've installed Linux on a VM to experiment, but I'm flying by the seat of my pants in doing so. Windows is the environment I'm most experienced in.
It's interesting that I failed to find Bibledit in 2020, when I was looking for a way to get the JUB and JBS prepared for Biblegateway and YouVersion. After looking at Paratext and deciding it was beyond my scope, we contracted Rob Benson, in GB, to do the conversion for us. He's no longer doing this for hire.
In addition to a hyphenation dictionary, I also need to update our USX files for the 200 or so corrections (primarily Spanish word changes) we need to make to our Biblia del Jubileo (JBS). So I guess I'm also asking if the desktop version is suitable for that task?
I would have thought that directly editing the USX files would be sufficient, but I remember reading where direct editing of USFM can introduce corruption. Seems to me XML structure would be difficult to mess up. Anyone's thoughts on that would be helpful.
