If you are looking for SOS Readers' Ads, you can access this FREE service using the red buttons displayed in the righthand column of most SOS web pages. 
These always appear directly below the tall skyscraper banner ad on the right (as shown in the example from the SOS home page).
Alternatively, you can use the direct URL: www.soundonsound.com/readersads
After you CREATE FREE AD or ads, and select which Category each should appear in, you can follow the status of your advert in MY ADS.- Once published on the site, if you sell your gear you can return to MY ADS and Delete your advert(s).
- All adverts auto-erase 30 days after being published here.
- If you do not follow the submission guidelines, the readers' ads moderation staff might delete an offending ad (sorry, but we do not have time to contact you about individual ads).
Use the Days selector to display ads from, say, 7 days (with or without a Category choice). Try search and it will find your words in any advert in any category.
You can sort the advert columns by: Description, Price, Location and clicking About reveals useful information about the seller.
We hope you enjoy using the SOS Readers' Ads service.
