Ok, seriously this has started to get to me and I don't understand why it's even happening. This kind of ties in with Osi's "Don't start a thread that's just another duplicate", but is different.
If you don't know the answer to a question being asked in a thread-don't respond! It's as simple as that. By saying "Um, don't ask me, I don't know ^_^;" does not help ANYONE. So just don't do it, lol. Replying to a forum thread doesn't help your level increase like... at all. It's in the hundredths place of helping you after the decimal. So there's no real reason to even do it.
So basically, just don't respond if you have no answer to a question being asked. And seriously, it gets annoying when people go off on a tangent from the original subject; like you say something and then start a whole conversation that has nothing to do with the thread! There is such a thing called PM's. Even an Instant Messenger! Use those to have full-out conversations, lol.
Ok, I'm done ranting...^_^; Basically, just stay on topic in a thread, and if you have nothing to say, don't reply.
