author meta/ information for authors without posts

Hello,
I posted the following on the ‘one its running/how’ to section of the forums, but I think it may be more appropriate here:

I was wondering whether anyone knows how to display the author meta/ user description, contact details, etc. in their author archive page, if they have no posts? I am currently just getting a 404 message for authors with no posts, and I would like people to be able to view their details, even if they have not posted.

I have tried this plugin, and any support threads I have found on the subject so far have not been effective.

Thanks for any help
