We have offered this ability for years via another thread here of course, but those offers were sometimes mixed up with other offers.
And too many members here were just adding links to all their current on sale lots. All auctions allow you to subscribe to new listings by any specfic sellers, so do that for those guys.
We do ask that common sense reigns here, and if you list a few interesting items, add a direct link to them - with a photo if you wish, but NOT the auction house photo links which will vanish in a few weeks, making the thread meaningless to everyone, thereafter.
Nor do we want to see 46 lots in a line etc, nor simply a general link to all lots you might offer .. this thread is for SPECIFIC lots that you have listed, that YOU feel might interest others.

A Hagner sheet of Western Australia duty stamps, a cigar box of 1d green KGV heads, or stockbook of Triangular stamps etc. That kind of thing is envisaged.
