EXTREME-ULTRA-SUPER-LATE-BUMP just thought that I should tell you that you bumped a dead thread but anyway welcome to the BeamNG fourms if you have any troubles just send me a PM.
Its a wonderful mod I support creativity for a beginner like this...but you still have lots to learn I can tell but still....you learn every day
Posts that show up in the thread feed page get lost overtime as people stop commenting on them and they get old or die out. A bump is when someone comments on an old post which then brings it back to the top of everyone's feed as it now has an unread comment. This may be intentional, but most of the time it's simply because people don't think to check the date of the last comment before they post their own.
