Mood for messages containing commands...

The same issue is discussed also in Thread:Portal_talk:Os/Imperative_in_option_messages?

Thank you for the link.

I have drafted a small piece on verb forms on the Translators' forum. Any additions/improvements are welcome.

Added some links. I'm not sure it is a good idea to advocate so strongly to ignore established conventions.

Feel free to amend wording. Have had a go at rewording myself also.
