We do not limit the number of threads a member can open in the marketplace. In other words, you can open as many services as you want so long as none of them are duplicate services. However, please be aware that every marketplace thread you open will require you to pay the $30 marketplace fee and you'll need to go through the review process with every submission. Also note that this means you'll need to renew all of those services each year.. September 2019 update DD For clarity. You must have successfully completed one marketplace thread application before submitting another. Where multiple applications are submitted they will all be deleted and the OP notified.
