Can I mention/tag through Socialdraft?

@ Tagging On Twitter

With the @ function in the share box you can mention people on Twitter (wohooo), so if you wanted to tag Socialdraft, you'd just tag @socialdraftapp on the write up for your post. 

@ Tagging on Facebook

You can tag Facebook pages on your scheduled posts. Before adding a URL, simply begin to type the @ symbol and the name of the page. You will see a dropdown appear. Simply select the page you want to tag.
