SECTION 5 - Miscellaneous -
WHAT IS MY KNIFE / GADGET / SPATULA / TUNING FORK WORTH ?!?!?!?!
In order to curtail potential abuse of membership privileges associated with the forums, questions regarding valuation of knives and collections are limited to those with a membership level which permits selling on this site. Accordingly, registered and basic members may not start or post in threads with such requests whether with the intent to sell or for informational purposes only. This rule applies throughout the site.
REGISTERED USERS - The first level of membership. If you have not purchased a paid subscription, you are by default a Registered User. As such, you are very limited to posting areas in the Exchange. You may respond to threads where you mean to purchase an item, or trade. You are not allowed to create threads for Selling or Trading (but you may respond to existing ads). You do have the ability to create Want To Buy threads
