I have no idea, to be honest. If you missed it, meaning you for whatever reason didn't log in yesterday, then technically I guess you could say you participated in it.
I highly doubt that anything really happened or was noticed or whatever. Just my opinion.
If people want to affect any change anywhere (not just Neopets), one of the best ways to do that is to sit down and write a clear, complete (with examples/suggestions if possible) snail mail letter and send it to everyone you can think of at that company. If you're polite, use good grammar and spell check, you will be taken at least a bit more seriously. And of course, it is good to write what is positive, what you really like about the place/site, etc.
I have written letters to different companies regarding different issues or problems I have had, or a level of disatisfaction with an item or product, and do include that I have used said item/product for (however long), what I liked about it, what the problem is with it now, and ask/suggest if such and such could be implemented so that whatever the problem is does not continue. I have always received a nice, polite response to those types of letters. Doesn't mean that anything has actually changed, as I am only one person writing. But if many people write regarding the same issue/problem, there is a chance that something positive will be done.
That said, and so I'm not labelled a chronic complainer
, I do also write letters when something very nice happens, if I get service above and beyond what I expected, etc. It's nice for companies to get praise and for the people responsible for the good service to get recognition (yes, I've worked in customer service).
