Hi, I got two suggestions for the OMSI Forums..
1. This annoys me most, I don't know German. And I've to guess what I press and do here at the forums!
Make English the default language, or make so you can switch language (German-English) at the forum itself!
2. Please make some nicer theme for this forum. No offence, but what currently is here is looking terrible. I feel like browsing at a forum that's made in year 2001, not 2011.
Not very attractive, and addition in a language I don't understand.
I've pretty good experience with forum managing, I've managed many before. So if you need help with a new theme. I could give it a try!
