@john-r: Not 100% sure what you are trying to say, but you seem to be hinting that if I was involved in organising one of these events I might feel differently? Is that correct?
Look, If I turn up at an event and they are out of maps, or don't want to take my entry, then that's fine, I'll just go for a run, but what I'm fed up doing, is going in and out of the fixtures list, and each event on the list, weekly, to see if, or when, they will be open for entries. I'm pretty much done with doing that.
My personal view is that unless there is a very good reason for it, if an event is public in the fixtures, then it should be open for entries. I've yet to hear any valid reason why that cannot be the case.
It would also help if the fixtures list itself showed if an event is open for entries, and if not, the date when it will be open.
