That was my fault. I didnt fully configure Group Manager so default permissions were pretty much nothing.
You should have normal permissions now.
Just for reference all players have some basic commands from this list:
http://wiki.ess3.net/wiki/Command_Reference
This is the listing of all that you should have. The ones from the link above indicate commands you can type and the rest are just things you can do. ie signs.use.* means you can place signs but warp means you can access the
/warp command. If in doubt, try it as a command.
