The CBB is a forum for conlangers.
"This is a forum for those interested in constructed languages, worlds, cultures and so on, as well as for those with a general interest in languages and linguistics. Despite looking heavy on the language part, this forum welcomes discussions about, say, concultures just as much as it does for conlangs!
When it comes to experience there is much diversity. Some members are professional linguists and/or very experienced at conlanging, while some might hardly know how to get started. It's important to know that regardless of prior experience, everyone is welcome here."
