Forum tags on Leagues/Events
This way players can quickly sort what they're looking for out of the whole list. A correspondingly clear & simple convention could be used: 3 letter car and car class tags, along with "all" and some 3 letter initialism for "random" or "various" or whatever.

Additional tags could be for start/end dates, e.g. a league starting now and ending next may could be tagged: oct-may, or 10oct-11may. If not already in the event's thread title.

If such a mechanism was added (requiring new event/league postings to have these tags; the car ones at least), I'd volunteer to help adding them to present postings that don't have em yet.
