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.
You might have noticed that you have a Vaadin "Home Page" if you have registered. Anyone can find you page by clicking your name on any message you have posted.
In order to make the pages have something useful, you should customize them. I wrote a quick tutorial on my wiki about customizations.
Wow - Henrik's member page is amazing :)
