Thanks dear medman
yes I agree with you, tebyan is a good & comprehensive site, u can find about everything here, i recommend this site to many people, i know it for a long time i use it, i learn from it participate in its competitions, collect points, & most of the time i used its interanet & free accounts & read its articles, i know it maybe for 5/6 years but my activity in this site started recently , and i"m glad from this activity.,i think here is a place safer than other sites & internet places.
but it has some defects & we can speak about them too.
so please every one speak about it & say your opinions.
thanks.
