To simplify things and help our users to be more productive, we have archived the current forum and focus our efforts on helping developers on Stack Overflow. You can post new questions on Stack Overflow or join our Discord channel.
If you're on LinkedIn, then you've seen that they have this new feature of being able to add "skills" to your profile. They've finally reached 1st (2nd?) normalized form for this instead of having people just enter arbitrary strings.
I've sent them some feedback to ask about how a skill is added to their list. Will let you know if I hear anything. In the meantime, LinkedIn users can manually add it anyway. Maybe if enough people all have "Vaadin" listed it could help.
