Anyone know about Facebook?

I have a FB page for my business and I used to be able to link(tag) when I made a status update by using the @ key. Now it doesn't work since they changed FB the other day. Any ideas?
A little more detail. We sell at farmer's markets which have their own page. When I want to post as my farm name, I would go to my business page, type in the information, use the @ key to add the market where I wanted the post to appear and "tag" them. The post would appear on my page and theirs. Now it no longer works.
