Hi Tony...

That depends on each blog software/service. You'll need to refer to their docs. Or, post on a more popular forum and ask how to add RSS pheeds to _______ blog.

Scrubz just creates the RSS pheed, how it is used and inserted is up to each service.

Yes you can but you'll need a program/script that allows for this.

My desktop program ZZ Tuel will do this for static html pages, and GodfatherBomb will do it server side. ZZ Tuel LTD is free and allows one "archive project".

There are many other applications that will also archive RSS pheeds.
