Hello due to the new plugin and popular demand we no longer have /minecraft:me, by this people can't spam caps, advertise, etc. yay! But /minecraft:me was used to share links. Links could go towards youtube, our forums, gyazo or imgur and most others could lead to a ban/mute although this was useful. Now if you want to show someone a thread or a picture you can't. I suggest we add /link <link> so when you click it it takes you to the link the person posted. Thanks Delta
Or just allow us to link anything in chat Sure, people will advertise, but people bypass that anyway.
Support, If you can find the plugin with /link or something like it. (I am unaware of any plugins that do that at the moment) EDIT: I found a plugin that makes it so links can be put on signs and then clicked. (Sign URLS) It is a Bukkit Plugin This Video might explain it more thoroughly.
You could just report the player on forums. I don't see any huge issues with it being removed. As for the link to forums, I suppose it would be nice to have that back.
