module to display all articles with the same tag?

[seadhna]

datahell, when I re-read all these messages, I don't think I explained very well my idea of "by the same author". You are correct that an author can write two articles about completely different topics; but sometimes users can be interested to see what else an author has written; e.g. a newspaper website will usually have a page for each writer: eg. https://www.theguardian.com/profile/patrick-greenfield
And you can see all the articles written by that author. Many newspapers will have an element on each article "Also by the same author" and list a few articles.... If readers like a particular author, this can be useful. I hope that explains better. This is just one little example of a use for a module that uses tags. The main idea I personally would find useful would be to list in an attractive way (with images): Our work in this country.... and to be able to show other articles tagged as a specific country would be amazing; rather than having to do this manually for every country...
