Comments system.

Issuing comments is very important because they are a very important element building trust to sellers. On their basis we know if a specific seller is trusted or not. Also the seller issuing a positive comment to the buyer can encourage him in such a way to next purchase. That is why every time you buy or sell anything on eBay you will have to issue a comment concerning the transaction carried out. 
Anyone who’s got the account on eBay has got his opinions bookmark on which there are displayed opinions and comments issued by other service users. Next to user’s name there is displayed in brackets a number of opinions and under it percentage of positive opinions. 
The buyer can issue a positive, negative or neutral opinion and a comment. Instead the seller can issue a positive grade and a comment. On the basis of issued grades there are defined opinions results. The positive grade causes adding 1 point on the user opinions bookmark and the negative grade subtracting 1 point. The neutral grade is 0 points so nothing changes on the opinions bookmark.
If you buy many products from one seller, you’ve got to issue the grade for each transaction separately. If all products were bought in the same week, seller opinions result will be increased or decreased by one point. 
Issued comments should be thought over, based on facts and most of all fair. Opinions can be issued only by registered users. 
If you want to issue a negative or neutral opinion to Super Seller you’ve got to wait at least 7 days. If your account is suspended, all negative and neutral opinions issued by you will be deleted. 
Remember! Before you buy any product firstly check seller comments and opinions. Thanks to that you can learn many things about him among other things if it is a trusted person and if he fulfills obligations concerning transactions, what opinions other users have on him. Checking and reading seller comments is a basis of safe purchase.
