Posting items on the auction site AND

I attempted to post an item on the BUY/SELL part of this site. For some reason it would not accept my password. Is separate registration required for it?

Phil. Would a count on the header bar next to the buy/sell of items present or alternatively a different colour of the icon if an item is present be possible. I rarely check that page as it is not a well utilised feature so an indication that there is a new item would be appreciated. Regards Alan Case
