In another thread i said:

I’ll post this as a feature request for a future version, and
also, I will take a look at the SF code hooks, to see if I could code
an addon to import RSS feeds to admin selected forums, groups or topics.

Such
a feature would also be useful in importing from other forms of Forums,
as well as news articles from remote blogs and news sites.

This would tend to promote user discussions, improve SEO rankings, and maintain active content for any Simple Forum site.

 Cross Posting, as I promised.
