Dear mods, since there are no longer any relay challenges, and people are using that tag for their achievement spam posts, please set the "Relay Challenge" tag to be hidden from the relay, like the "Greetings" tag is. Ideally, you could also rename it to "Relay Achievement" to be clear what it is. This will significantly cut down on the pointless relay posts.
Thanks.

Dear mods, please hide the "Relay Challenge" tag from the relay, like the "Greetings" tag is. Isn't that the whole point of that tag, to keep achievement spam hidden?
