Is there a plugin like this? [READ]

Is there an plugin that lets you create your own Join sign.

Like survival games you have these : |[Sg 1]| Signs.
| 13/24|
|? Map|
|[Join]|

I downloaded mini game plugin that don't have join signs already in it.
So i'm gonna ask the community of Bukkit this question:
( Is there an plugin that kinda works like this:? )

Lets call the plugin.. Join Signs.

* Heres the tutorial for the fake plugin:

* First You have to find a place and write
/JoinSigns createwarp FartGames (Thats were you are going to spawn when you click on the join sign)

* You have to finish the mini-game without the already inbuilt join signs.
Lets say the only way to join that mini game you have to do /fg join since there is no join signs.

*Now you have find a place for the join sign. and you are going to write this on the sign:
1line: [Name of minigame] This must be the name of the warp you created.
2line: [Max players] if you write 0/12 it would only allow 12 players to tp to a warp you created.
3line: [What ever you want] You could write the map or the one who made it. idk
4line: [ [Join] ] When the lobby was full it would have stood [Full]

*Now you have to add commands to the sign. when you click on the sign its just like you wrote a command. and remember since the only way to join the mini-game was to write /fg join you must add that command to the sign like this:

1.write /JoinSigns select
2. Right click on the sign you wrote the name of mini game and max players etc.
3. Once you have it selected write /JoinSigns add command /fg join
(You can add as many commands as you want)

*And then everytime you click on the sign you would be tp'd to a place and you joined the mini-game
and then it would say [1/12].

*Heres an example of what it could look like:

So im asking again
Is there a plugin like this somewhere?
Please someone answer it would be very usefull

If not..
I hope you guys liked this idea

 

im sure i saw a plugin like this somewhere, but i have no idea what it was called. (not much help in know. sorry)
i think it was for, like a hunger games plugin or mob arena or something.

 

I am looking for this for a long time but I'm affraid that big servers use their own plugins to do this.
