Strategy suggestion re: theme versions

I have certain threads set to show me follow-up posts in email alerts. So I'm seeing so many new messages in threads about old versions of Atahualpa, and of course we all see Juggledad and Larry continually asking people, "which version of WP, which version of the theme are you using?"

Wouldn't it be better to require people to first update to the newest, stable version of the theme (and WP too, probably) before asking their question? That way, the moderators and the rest of us who like to help would be dealing with only one, current theme, not having to figure out what the differences were months ago.

Threads relating to old versions of the theme should be closed so that no new posts could be added to them. People should still be encouraged, via sticky posts, to use the search function to find answers, and of course, the answers will be different sometimes depending on the theme version they are using. That's why it seems essential, with such a backlog of old versions, to require everybody asking questions to at least be up to date on the theme. The moderators could put a note at the end of old threads pointing to a how-to about updating the theme.

What do you think? Is this a good idea or not?
