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](http://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 O. [http://smpl.se](http://smpl.se) ---

The aggregation extension doesn’t modify any data/tables/etc. Use Subversion to check it out or export it into vendor/extensions/aggregation, then restart Radiant. You should then have the tags available. Either way, I would recommend upgrading to RC2 or the ‘edge’ of mental. I’m not sure that RC1 has all of the features needed by the aggregation extension, but let us know how it goes! Sean
