Danoosh, ever heard about an expression that says:
"Don't look the teeth of a given horse" ?
If you haven't, this expression means that you should not complain about something that been given to you, freely. You did not pay, you did not asked for it... it's like a gift. And isn't much of a good manner, to complain about a gift, is it?
And then, you come to this thread and post, for the 1000000th time, (means you have said it 1000000 times already), that they should fix the lag and anything that you feel like that there's need to be fixed. Ok, you said please, but everything you said before, and how you end the sentence, makes your "please" sound useless.
Just look how the same suggestion can be said in 2 different ways:
"For the 1000000000th time, I see lag and disconnections there, Firewalls and ports are OK. Please fix it for the next version."
"Hey, i am also experience a lot of lag with this, and i made sure my ports are open, could you guys please put more attention to it when working for the next version? Thanks"
And that's not about how good your english is, but a matter on how you talk to people.
