DNS Belgium, which runs the .be ccTLD registry, as well as .brussels and .vlaanderen, has been running a forum for registrars for several years.
Membership is open to .be registrars and currently it has 15 members. Members “represent the full .be sales channel of 430 registrars. At the meetings you are the first to hear about our innovations, new product developments and strategy proposals. We include your feedback in our further decisions and work on the quality and evolution of the .be zone together with you.” (source DNS Belgium)
In 2019 9 members’ terms will be up, so the registry is seeking applications from registrars who are interested in joining.
The group meets 3 times a year either in Leuven or Brussels.
If you’re a .be registrar and want to find out more or wish to apply there’s more information on their site here.
