If you mean the actual SpongeForge version 2477, that is very outdated, if you mean the SpongeForge version for Forge 2477, then make sure you state both next time.
Either way the answer is no, this plugin is horribly outdated, looks like it was last used for Minecraft 1.8.8.
I haven’t seen any plugin which puts in timed messages for the message slot above your hotbar, but there are plugins for the main chat, I personally use PixelAutoMessages. Or there is a plugin which gives an announcement title which you could use in conjunction with CmdCalander to create auto message your players.
Hope this helps.
