Just saying, not everyone can keep up with absolutely everything. We have lives outside of Beyblades too. If some people happen to miss something, then why chastise them because they can't divert their lives for long enough to keep 100% up-to-date? At that point, you're just being rude when you call them out for not staying informed because they're in a situation where it's either not possible, not feasible, or they're too young to be thinking about that sort of thing to begin with. Let's be honest, kids don't think about this at all. They just go "Ooh, cool! new Bey!" and go off on that for as long as their attention span allows. You can't blame them for being kids.
Same goes for post preview tools and the like. Most of the forums I'm on automatically ping you when you try to post a message when another message has been made between when you started and when you finished, allowing you to make any changes you find necessary. This is the only forum I'm currently on that doesn't do that. Also the fact that I started typing with only 3 posts (counting the OP) in the thread didn't help, which meant that yes, even that "same question from 2 posts ago" didn't exist when I started typing.
I get that it happens a lot, but try giving people the benefit of the doubt instead of yelling at them for being underinformed. It's just not feasible for everyone to know everything, and not everyone is willing to read through every post to see if something has already been answered or discussed and head straight down to the comment box the moment they see something they find interesting.
