I know this topic isn't for promoting your OWN ebay-auctions,
You're right - no linking to your own auctions is allowed.
I'd hate for this thread to have to close because the content moved towards "auctions are being promoted" instead of "customs being appreciated".
Just remember, it's OK to talk about cool customs you see on eBay, but there isn't always a need to post the link in here. People are smart and can usually find the actual auction on their own by a quick search.
