请帮我看看这段话有没有语法错误,

Everybody can find stuff which is worth to own in Trade Me.(我觉得你要表达的意思是：在TRADE ME可以找到值得拥有的东西）或者Everybody can find necessary stuff in Trade Me.(能找到日常的必需品）
food不要加S
改动如下:
Everybody can find necessary stuff in Trade Me.Such as food,clothes,bags,cars,etc.Buyers and sellers can exchange their view,express feelings,and sharing information mutually through the trading.So Trade Me is not only a business,but a way to create new friends.
再问： 十分感谢 再帮我看看这段话用不同的写法要怎么写更好些？ Firstly,part of its incredible popularity stems from its being a uniquely kiwi site that keeps it all local, tapping into our highly developed banking and distribution systems. Secondly, the wonderful collections of communities that constitute the real Trade Me share knowledge eagerly and talk among themselves for mutual benefit.
再答： Firstly,the incredible popularity stems from its keeps it all local, connecting our highly developed banking and distribution system. Secondly, a large group collections of communities that constitute the real Trade Me information sharing.
