I explained myself badly. I meant attempt a post in the Premium Support area. If you do not have an account there it will tell you the charges.
I was assuming the same conditions that used to apply about removal of the Powered by Nabble link still do. Without premium support you should still get an official response here but it will be slowe and does depend on the volume of work generated from Premium Support requests.
Volunteer Helper - but recommending that users move off the platform!
Once the admin for GregHelp now deleted.
