One of the most anticipated features the new BMC Communities brought, aids us go email-less and really fast is the ability to point communicate with users Twitter style, on the Community directly by at_mentioning them on your content.
Start by typing @ and then the person's name/username. Now with the huge userbase we have, sometimes you would be faced with the case of multiple people with the same name.
Tip: Conversely, for you to be easily found, please make sure your profile is complete with your first and lastname.
In the same way you can include Content, Community or a Group directly on your content without having to select and hyperlink your text using the editor. As the system suggests you (in the screenshot above) type the space name or Title of the content and join multiple words using an underscore. Very useful for content curation.
Hope this tip help you locate the right people every time and include the content and places that would matter the most in your Discussions, Documents or blog posts. For more tips, make sure you follow Using Communities.
