Groups such as Builder, Scripter, and so on should be mentionable in topics by users on the DevForum. For example if in the ‘Collaboration’ category someone wished to collaborate with, or hire a Builder, they can mention the group in the topic by doing @Builder or similar.
This would be beneficial in the case that they could attract the attention of a specific group of people that are needed, and also at the same time someone looking to be hired can easily keep track of topics where a certain group of individuals with a specific talent are required.
The downside is getting a blue notification dot every time someone mentions a role. (However I don’t really find them to be that annoying). A solution to this could be ‘muting’ notifications from group mentions.
