Dear Vahed,
you can call me NADA. it's not my name and even it's not a name at all. but if it's hard for you to write my long id you can use it.
i read all of the posts and about the sentence which you couldn't understand - which was written by bakhishman- i think he means that: i'm not satisfy of my english and i never will, BECAUSE I always want to learn....
cause means because in informal speech. of course i'm sure you knew it but just because you couldn't understand the sentence i said this.
and about topic actually i couldn't understand what is our main topic here to discuss about. everyone suggested sth and there was no agreement as i noticed. so i'll be glad if someone fix the topic and let us to talk about it.
thanks everyone
