What is a "Business Request"?
A "Business Request" is an exchange request, where a member request to another member to trade items (goods or services).

You can send a "Business Request" on any item by clicking on the "Business Request" button of the item. When you do so, you will be required to select the Item(s), or either entering the OGV amount, that you want to give in exchange. Please note, that if you have not published any item yet, neither nor you have purchased OGV virtual currency, you will not be able to complete the request.

Once the request is succefully sent to the other member, he/she will receive a notification of this request in the "Notifications" icon along with another notification in his/her Profile page on the "Business Request" button of the corresponding item.

At this point, the other member will be able to choose whether to accept this request or not, as this request does not constitute any obligation to the other member on accepting it. The "Business Request" can be accepted or rejected by the other member without any commitment.
