Have you tried to use the "SubSim Smart Dark" skin l02turner, or are you using the "Compass Lite" or "Admiral Blue" - or perhaps you are on a mobile device that only uses the "blue", in which case, the orange text 'bleeds' and makes your eyes hurt - but it does stand-out nicely on the Smart Dark. When you find text you can't read so well, just click and drag (finger swipe, whatever) to select a post's text, and the "high-lighting" of that will make the text legible...
btw, if you go to use any of the torpedo mods in the mod package and then drive an S-Boat, the game will crash as the torpedo goes to explode. Known issue with those mods, so don't use them, or don't use the S-Boats if you do add the other mods in.
