Perhaps more to the point where would you want the line to be drawn between bronze and silver events?
According to the ECF Articles/Bye-Laws, an affiliated League or Congress is:
A Congress is an event that primarily organises events on an individual basis.
A League is an event that primarily organises events on a team basis.
It seems natural to extend these definitions to the concept of membership.
My answers aren't gospel, but this would be my interpretation:

Suppose a local league runs a 5 round individual competition held one game a night on the first Monday of the month Oct - Feb at a fixed venue. Is this a congress?
No, it's a League-internal event, if you like. Bronze.

Falling numbers tempt the organisers to try a different approach, so the same competition is now held over a single weekend at the same venue as before. Is it a congress now? Suppose the venue isn't available Sundays, so the competition is extended to six rounds held three each on consecutive Saturdays. Congress?
Still no if it's an event closed to the league. Bronze.

Is a congress necessarily an individual competition, or can you have team ones? Does the style matter - swiss/all play all/KO/jamboree. We have a two round single evening quickplay team jamboree for teams of four. Congress? Would it be any different if it were longplay played on a Sunday?
Yes, a congress is an individual competition according to the ECF's Articles/Bye-Laws. Anything played in teams (of greater than 1

) is a League. The two-round single evening rapidplay jamboree is a league, so requires bronze.

Is a congress in some sense an open event? If a large club holds it's club championships over a single weekend is this a congress or can it still be what might be termed a bronze event? Does it make any difference if they invite a few players from outside the club to add interest? Who decides who is a member of the club? - not all leagues demand lists of members to be sent in triplicate to the north pole before the start of the season.
The club championship is club-internal, so it's bronze. A club-internal individual event is a type of congress. All congresses that are not internal in some way are silver. The invited outsiders make it a non-club-internal event.
[quote="Martyn Harris"]Does size matter? Would 6 players getting together and playing an all play all at one of their houses over a weekend be participating in a congress?[/quote[
No, that's a congress. Silver or Pay to Play.

There are bound to be some loopholes in the above if you think creatively, but using the team = league, individual = congress logic, it should be quite easy to work out.
