Reblog from any blog to any blog

[Contro]

Specially from blogger, wordpress.

Perhaps a free rss feeder manager ?

I would like a tool to aumatically repost or reblog from a blog to another.

By example :

firstblog.blogspot.com
to
second.wordpress.com


Is it possible automate this easily ?

Best Regards

but when i try to share (i think only is possible in manual mode) the only possibility is to share to wordpress blogs I admin.
Recognize allmost any feed. I don't get with Tumblr, but all the rest.
