[TYPO3-english] Extension for newsletter

[Sergio Catalá Gil]

Hi list, 

could you recommend me some extension through I can build a newsletter
with different articles from extension tt_news?

The idea is a backend user (with enough right access) could select
easily the articles he/she wants and put them in a block. 

I've been using direct_mail until now but I'm only allowed to define how
many elements are used in each block, not the ones I want. 

Thanks in advance, 
Sergio
