This is a small plugin that has 2 commands - /sas and /yirk. This plugin is just a toy and this is version 1.

/sas is a command that gives you 1 empty block, for free. This does not require operator rights.
/yirk - it just writes "yirik pirik alert!!!!!!!!!!!!!!!!!!!!", sets the time of day to 12, and the player is in survival mode.

Everything, for more, the author is not capable of, you can play around with the mod, and score on it.
