About:

-Lock any sign:
By right clicking to a sign while shifting you lock it, the text on the sign changes to a different text. After right clicking to it again the sign get's the original text back.

-Locked signs can't be breaked:
No one can break signs that are locked.

-Update alert:
The script will alert you if you have a older version of the script.

I will not stop developing this script until I have ideas.

Look of a locked sign:

At 3. line is the name of player who locked it.
