@Holoway: For random chit-chat, there is a forum category called, oddly, Chit-Chat! https://forum.vivaldi.net/category/15/chit-chat ! For slightly more focused (but general) discussions, there are tech, security, and games discussions in the Lounge. https://forum.vivaldi.net/category/37/lounge .
Otherwise, there are categories for each platform, for all platforms, and for various languages, in which to discuss questions, problems, hints and tips concerning the browser. Explore the Forum! Also, check out the Blog for the latest news and latest (not yet fully released) versions.
And, Welcome aboard!
