Create an updatable content link from Tumblr

Could you please advise on how is it possible to create a link from let's say Tumblr or other blogging site and put it into my site's section with the news. So the idea is to let other people edit news in Tumbler and automatically update them on my site.

Any suggestions are at great value. Thank you.

You'll need to do a search on the web for something like "Embed Tumblr into html website" or variations of it and find that answer. In order to embed other systems of information on a site you usually need a code from that provider. Tumblr may have that information on their website as well.
