ok so we were a little behind getting the system integrated here on shine, but it should be in full effect now! you'll see at the top bar, the little flag icon; when you get an alert, a little green circle will pop up with the number of alerts you have. just click on the flag and you'll be taken to your alert box. you can edit what alerts you get and how you receive them in your control panel. just click 'alert settings' on the left side of your panel and you'll get a whole list of ways you can receive various alerts.
on that note, if you don't know how to use the alert system, it is incredibly simple. copy the username of the person you want to tag exactly. so for tagging me, its ☆ COSMIC PRINCESS ☆ -- a warning that, sometimes, a tag will not work in preview, but will work when you post. and, sometimes, a tag won't work at all; it all depends on what characters are in the person's username. in order to fully tag someone, you can either do it manually and type out @[FULLUSERNAME] or look up above the post, you see that button that says @TAG on it? click that, paste the person's username into it, and the board will do it for you!
you're all free to use this thread to test it out, you can tag yourself, tag me, if you need to practice using it. so feel free to tag anyone in anything you want them to see!
