When you buy or sell something on the Euro-Nova site, leave feedback for the other person using this forum.
If the person already has a feedback thread then add to that one, if not then create it for them using the title of "PERSONS NAME Feedback" for example, "Bobbybrown Feedback" or "Bobbybrown (Dan) Feedback".

This should help others and especially new members of the site to know how good certain people are at dealing with others in a sale like environment.
I know quite a few things have been sold on the forum lately, so come on, get yourselves posting feedback for those people.

Also, if someone has been very helpful, either through PM or other means then you can also add feedback for this in their thread too.
