Buy & Sell is a 'members only' area where people can get together to - buy and sell!
Guests (unregistered visitors) can view what's on offer and wanted but cannot see contact details for buyers and sellers.
You can register via the 'Shopping Cart' link on the main menu or from the forum itself - the 'Create an account' button at the top. For direct deposit details, see here.
Once you have registered and paid your $20 annual fee, you can add entries to the marketplace and see the contact details. Although I moderate the postings, I have nothing to do with negotiations between buyers and sellers.
It's that simple.
There are no fees or commissions once you've paid your annual registration.
If you have any questions, contact me via the contact tab on the left.
Once you have registered and logged into the forum, the first page will look like this: note that 'Welcome Guest' has been replaced with 'Welcome (your username)'
When you click on one of the categories (In this case 'Buying') you get this screen, showing the posts:
Click on the post of interest and you get this (without the big arrow!):
When you click on the 'avatar', you get details of the person who posted - including their email.
This means that you can respond to them on-line (via the 'Quick reply' or 'Reply' tabs) or email them direct.
