RSS feeds we are following should be useful sources to create new leads or opportunities.

I made some trials to import external links into the web pages of the blog without success.

Is this an implemented feature? and if yes how to make it work?

If not, could it be implemented as a standard module?

The wokflow : RSS feed is imported into a new blog page> creates a new lead or opportunity > based on new lead/opportunity a new product is created when the Rss is mentionning a product which must be presented to our customers.

The new blog page is allowing customers to comment it (comment window and possibly a questionnaire) and finally to request a quote for the product.

EDIT

A highly interesting solution to handle RSS feeds and to make them available for a website (populating a Newsletter page for instance) is WP RSS AGGREGATOR
