Mentions are names or usernames prefixed by @. Mentions trigger notifications for whomever is mentioned. We recommend that Community Members use mentions to continue conversations, acknowledge peers' ideas, solicit others' expertise, and encourage other Community Members to contribute.
To mention a Community Member, begin by typing @ in the Post or Comment editor. A list of Members will appear in a pop-up menu. Continue typing the full name or username of the Member you want to mention. When their name appears in the pop-up menu, select it. Upon clicking the POST button, the mentioned Member will receive a notification.
For more on mentions, see the learner guide.
Hashtags are words prefixed by #. Hashtags thematically categorize Posts and Comments and enable hashtag-based filtering. Unlike Topics, hashtags can be created by any Community Member. We recommend that Community Members use hashtags to categorize content, organize contributions, facilitate filtering for themselves and their peers, align themselves with a position or movement, and join large conversations for which individual mentions are impractical.
To add a hashtag or use a preexisting hashtag, begin by typing # in the Post or Comment editor. If at least one hashtag already exists, a list of hashtags will appear in a pop-up menu. Continue typing the word you want to use as a hashtag. If the hashtag already exists, select it from the pop-up menu. If the hashtag doesn't already exist, simple hit space when you've finished typing your hashtag. Upon submitting your post, other users will be able to select your hashtag from the pop-up menu.
