I appreciate your response Fess. However, from your post I think there may be some confusion. The reason I say that is (and I may have mislead you in my wording at one point in the original post) you talk about 'FSO scenarios'. They are two different events. "
FSO" is a type of Special Event held on Friday nights. "
Scenarios" are a different type of Special Event. While they are somewhat similar, there are some significant rule/format differences. My post was only trying give a nod of appreciation to the people who provide FSO's, but the main focus was on Scenarios.
It's also possible, from the sound of your response, you might even be referring to one of the other, smaller Special Events like AvA, or a Snapshot, considering the small number of people you found there. FSO typically involves 150 to 200 players, while Scenarios used to have as many as 300+, but now are around 150 or so. The AvA doesn't usually have more than 2 or 3 dozen players (at least that I've ever seen), similar numbers for a Snapshot as well.
Further, while Scenarios do allow walk-ons on the days (usually 4 Saturdays in a row) of the event, they are eagerly greeted and asked which side they want to play on. Unlikely you would have been ignored, unless you were way, way too early for the side C.O.s to be on. FSO's on the other hand, don't allow walk-ons at all. You must first contact a participating squad and ask to join them IN ADVANCE of a Friday night's event. Most squads in FSO are also glad to accept additional pilots, but you have to have their permission before the event starts.
Not to belittle your response, I am a bit skeptical that what you tried to join was actually a Scenario, but more likely one of these other events. And even if it was a Scenario, as I mentioned, in the past some players were put off by how large the event battle spaces were, and occasionally a squadron had a hard time finding a fight. But the most recent Scenarios have been purposely set up to alleviate this issue, and combat is now exceedingly easy to find. In fact, it usually finds you whether you're ready for it or not.

The last one "Dneiper", held last summer was extremely intense with non-stop action for everyone. I don't remember a single complaint about being bored.
Further, the new 12 hour in one day format (as opposed to the 4 Saturdays format) has been run once before with great success. This next one we expect will be the same as it was specifically asked for my the players. You will be able to fly anytime you want during the day, for as long or as little as you want, you can come and go when you want, all day long. And with UNLIMITED number of lives. Plus we're expecting more pilots at certain times for this one because with the 12 hour timeframe, European players will join in as well.
In any event, I do appreciate your responding. If I can help clarify anything or provide you with any more information about the Scenarios, or the FSO's which I play as well, please just ask. Handle is the same in the game as in here.
