Q: How do I put an avatar-link to another user into my comment/submission?
You can link to another user by writing the following:
This will display a clickable avatar for the user "USERNAME" along with the name. Clicking the username will take you to their user page.
If you want JUST the avatar picture without the username or popup menu, use this:
So for example, to link to Toumal, you would write :iconToumal:
Note: The username doesn't have to be uppercase. The "icon" part MUST be lowercase. If the username has a space in it include it as in :iconFirst Last:
