Supress Tags with count of less than 2?

Hi, because I’m using a lot of tags for actors, directors etc on my film review website – I have a lot of tags where there is only one of that tag until I post a review on another film that also contains that tag.

What I want to do, is supress the displaying of all tags where there is less than two of that tag.

I’ve have got to this work on a single post page by editing single.php in my Mystique theme, but it’s not working on my index page where multiple posts are shown.

I would like to supress the tags at the lowest level possible as I am using AZindex plugin to generate a page which includes all my tags. I would like that page also to only show tags which have a count of more than 1. I’m wondering if I can supress it at a low level whether I can avoid having to edit the files in AZindex.

If it is not possible to edit so that AZindex only picks up tags that have a count of more than 1, then I would at least like to get it working so that my index page blog posts show up the same as single post pages.

Any help or advice would be greatly appreciated. Thanks
