i am an organizer.
i communicate our league and events on the leagues page here
the answer is perhaps to have a tool like this :
https://worldsimseries.com/
having a page wich list the races with a countdown, a beautiful posters, all informations, way to register and results
when i find this webpage, i was stunning !! all races in one page, all in attractive design !
and i instantly think about Live For Speed ! why not have a tool like this ?
but better ..
the negative i found in this page is the fact all is automated .. you register without discuss or agree a rules sheet, you came on the server, race and leave without communicate... it 's like a race self service. and no control about ping etc ...
but the idea and the design is very attractive, the information is here about what and when !
@Scawen : you asked what the way you could explore to help us fill our grids, hope you will take a look and feedback what you think about.
