    @ Unreal: Forum mantığını kavramaya yönelik bir örnek olduğu için o kısımlar yok. Hali hazırda forumlar zaten mevcut fakat onların karmaşasından mantığı kavramak çok zor olur. Kendi forumunu yazmak isteyen site sahipleri için ideal bir örnek...

    @ admin: evet farkındayım zaten çok güzel bir örnek bu ama üyelik sistemide entegreli bir şekilde anlatılmış olsaydı geliştiriciler için çok güzel bir kaynak olurdu :)) ama kendi yazdığım üyelik sistemini buna entegre etmek de çok zor değil.
