Personally, I'm happier with the new layout, and I am a frequent reader of all Racing Club Events. Both layouts have their pro's and con's but to me it is not much hassle to go to the games of your choice for
ALL the info about that game, rather than have it spread around. Like Stuart has said, when I want to see all events in one place, I check the Calendar, much easier that way.
To illustrate an example of how the old format could cause people to miss events:
In the Rally club, our Events covered an International audience (Rallys are set across multiple timezones) but were listed in the European Racing Club. That means that any American or Australian members may not notice these Events (regulars knew where to look though) or we had to duplicate our Event notices etc, to help expose these Events outside the European racing club Forum.
Biggest downside I see - besides having to look at 4 or 5 forums instead of 2 (for club races) - is that the completed race events will be mixed in with and push other topics off the page faster.
Also, as a Race Organiser, whenever i wanted to check the history of Rally Club Events, I had to search through multiple pages (often more than 10 pages) to find the past Events. Now all Rally Club Events are listed together, much better to research.
Each of us may have different preferences, but the differences / inconveniences are only small, and I personally prefer the new arrangement.
