You'll get plenty of practice with English here and become better. You need not worry. If you have any trouble understanding do not be afraid to ask for a better explaining.
Do not become discouraged. We are family here at Subsim and help each other.
I will report to you how well the XXI Water Streams works. I think I finally have my mods installed correctly so I can play GWX now!
Racerboy's U-Boat Exhaust mod is very well liked by many. You may want to create a version of your XXI Water Steams with the Exhaust included.
Thank you for your good work!
