Once you have offered at least two comments to others you are in a position to then ask for some comments yourself.

You do this by first of all clicking on the request comments button (see below)

When you have clicked on request comments you will see a screen which is similar to that below.

The first thing you need to do is pick what site you want your comment on followed by what post. When this has been completed you need to state how many credits you wish to use on comments (there is a sliding scale which will show you how many you have available).

Once you are happy with everything the last thing you need to do is click on the big green button that says Submit My Request For Comments.
