We are currently not, nor probably ever will be looking for staff. Staff implies that you have a paid position on the server. The Minecraft Server Community has greatly exaggerated what Staff means and the importance of it.
We are fortunate that our community is full of helpful players who aren't "staff" or volunteers. Though we do have some people who volunteer in an official capacity as moderators. We aren't currently looking for more moderators at this time.
I keep getting "kicked for flying" when I'm not flying.
If you have a poor connection, or experience a lag spike, your client may send incorrect coordinates back to the server. The server interprets this as flying because you are moving into a position you normally wouldn't be able to access.
There is no punishment for this, simply log back in and continue playing. Though if you have a poor connection, you may continue to get this error.
