[Radiant] Aggregation tag and upgrading questions

[Martin Olsson]

Hello,
I would like to start using the aggregation extention that was  
mentioned on this list a while ago. I'm running Radiant 0.6 RC1 on  
Site5.com and I would like to know how you guys think I should go  
about uppdating the installation and adding the aggregation extension  
without losing any data.

I want to use the aggregation extension to aggregate posts from my  
different project blogs on the front page of my site, and to provide  
a combined rss-feed.

I'm still new to Rails and Radiant, as well as to Unix systems in  
general so I think I may need some hand-holding. (Not a lot, just a  
little.)

Regards,
Martin Olsson
