Hello. I don't know if there is something that I can help with in the process of posting and updating the CAR rules.
Nevertheless I noticed that the front cover (first page) doesn't have all the box covers from the series and since some are just released with Spielbox only, there are only some tiles as image. I think that since this is a rule booklet in English, we should try to include all the Rio Grande versions and only include the Spielbox expansions, since they are exclusive. again, we should detail the collection as much as possible (for example: include all the expansion in "Graf, König und Konsorten" since all, are published by Rio Grande). Just a suggestion...
I already created another front page for this rulebook and I'll add a link here:
