Any serious LS is going to have that rule.
I like to think I was in a serious shell in xi, and it didn't. More common were other serious shells which would certainly not allow you to be in another ls that actually did stuff, but wouldn't care if you wanted a convenient way to talk to some friends who had helped you get your AF, or who you had brought to the game with you, or whatever. And then, yes, there were shells that did it your way too.
Anyways, this is why I never applied to your ls here despite your being clearly the most accomplished one around that I'm aware of. I Came to the game with a friend of six years or so from xi who made herself a little chat ls, and I think it would be ridiculous to abandon people I know well to get in a shell that does well (in fact, caring that much more about virtual goods and firsts than people would make me a bad person imo, and would be a good reason to reject my application).
The basic fact of the matter (imo) is that the difference between doing things great and doing things well in these games is pretty small, beyond the satisfaction of getting it done in style. The events here aren't /that/ intricate, and most decent groups of people will eventually figure out how things get done. You've all done the best, as far as firsts and such go. But the rest of us will catch up.
Don't get me wrong. The satisfaction of doing things with style is great and worth having. It's pretty much the number one source of enjoyment in the game. But still. Somethings matter more.
My first post, yay. Not meaning to be overcritical - your ls sounds great in about every other way. I just wanted to say something since the topic came up, and I'd thought about this in the past.
