Do you use marketplace section of forums to buy and sell services?

[Nomad]

I am active on many forums and most of the forums where I am active have marketplace sections where users are allowed to buy and sell services and products. I have not only used these marketplaces to hire people by also sell my products and services. I sell my digital services writing, website management services, etc. I also sell my websites. I also hire other users to work on my sites and sites I manage for clients. Do you use marketplace section?
