Service creators, please look at your forms from a lay user's point of view, especially if you're a relatively unknown company/name and are venturing into something you're not known for. On the signup form, there is a checkbox with this text: "I'm planning to use Vivaldi.net Mail and/or Blogs (requires phone verification)." What exactly is Vivaldi.net Mail? How is anyone supposed to know what that is? How is it different from Vivaldi Webmail? What exactly is Vivaldi.net Blogs? Is it referring to reading Vivaldi.net's blog (sounds silly) or creating blogs there (how?) or commenting on blogs there? Can I signup for Vivaldi webmail without checking this box? Also, does Vivaldi Mail support IMAP so that I can have my own copy of the mails and use other standard apps to access it (without having to solely rely on webmail)? Lots of questions...and concerns!
