I wanted to let you both know that as of v4.16.0, DomainMOD now has multilingual support. Currently it supports Dutch, English (Canada), English (United States), French, German, Italian, Polish, Portuguese, Russian, and Spanish.
I also wanted to thank you for your effort Mafiom! I had already started playing around with multilingual support, but unfortunately it fell down the priority list because of other features that were ahead of it, but earlier this year I was finally able to buckle down and finish the implementation... and then life got busy again and I kind of forgot to actually push the release out for another 6 months :P Oh well, at least it's done now!
