Hi there!
In https://steempeak.com/ you have a feature called Crossposting that let you publish a post initially posted in one community be "re-posted" in other.
In https://steemit.com you can resteem a post made in one community into your blog, otherwise your "blog" just show post not "community engaged", to view all your post there are the option "Post".
Not sure if I answer your question ;)
