I've just uploaded a large amount of magazine contents and cover scans for several US magazines including Road & Track, Car & Driver, Motor Trend and Hot, that were kindly provided by Jim's Mega Magazines. https://jimsmegamagazines.com/
I've made some minor improvements to the website for selling magazines.
Now on the magazine issue page, a list of any members selling that issue will be shown on the page with location details and a button to contact the member.
You can edit your profile and add details about what payment methods you accept, and what postage and pick up options you offer. These details are shown on your profile and with any issues you are selling.
People still need to register on the site to send a message. This is to (hopefully) prevent spamming.
