This plugin is a great idea. Players go through a lot of work creating signs only to lose them if the sign gets destroyed or the server wipes. This allows players, whether they hand draw signs or use Sign Artist, to manage their signs, and reapply them again and again as often as they'd like with such minimal effort. 

Every player that has learned about this new feature on my server has reacted with pure joy.

Great plugin, very useful for admins like me who apply signs in bases for offline players as warnings to follow the rules or as notification of additional rewards. Good for players too. Just today a player told me about an art gallery he'd created on my PvE server. There were a LOT of images they'd used and it would be nice if this plugin could do more then just 25, with multiple pages being ideal.
