The MarketPlace - Original Post Editing

Is there a way that you can give service providers in the marketplace the power to edit their Original Post, regardless to how old it is?

Some of these threads seem to last for years. It would be nice if the service providers could:

• Change their prices on packages
• Update on services they may have offered to begin with
• Add-on new packages
• Take off packages that didn't work out for whatever reason

As a buyer, I just find it a real pain in the ass to read though 20+ pages before buying something. And I'm sure the sellers are sick of the same questions over and over and over again.

Thanks.
