Relevant / similar content

HI,

I am having a problem with relevant / similar content modules. They operate with the same content type only, which is a great inconvinience.

In other words, I have nodes of different types: articles, news, interviews and etc. The modules create blocks of the similar content but such blocks include nodes of the same type as the main node only, for an article - articles, for news - news and etc.

Would be grateful for any comments.
