Direct links simply to Ebay aren't what the Trading Post is about.
This section of the forum is - like Amibay - a place for folks to offer (or buy, or trade, or simply donate for pickup) retro-computing hardware, software and peripherals outside of an auction environment.
Site members can declare interest and communicate via Private Messaging tools to work things out.
If this became a place to simply drop links to Ebay, the Trading Post would lose its meaning. Most of us here already have a multitude of Ebay Alerts we receive emails for on a daily basis about new things that pop up over there we might be searching for.
