In some examples, messages that are not associated with a high priority or a low priority, that is, “normal priority” messages, can be represented by user interface elements that are associated with a particular size, color, font, animation, etc. Such a presentation can be a “default” presentation or a “standard” presentation. In some examples, user interface elements associated with high priority messages, or messages associated with a first priority, can be presented in a different size, different color, different font, different animation, and/or the like, for example, relative to “normal priority” messages. The message posted by User F in the user interface 144 is an example of a high priority message and the user interface element associated therewith is presented in a different color than the other user interface elements associated with the other messages. In some examples, high priority messages can cause a user interface element to be presented in association with the communication channel, direct message, and/or the like with which they are associated, for example, to alert a user that there is a high priority message.
