when I just want to put my fist through my screen. Ran into a problem 
using groovy after installing. Went to answer.ros.org like a good little 
ROS user to ask my question after not finding a solution there. Then I 
get, 'Could not post, because your karma is insufficient to publish 
links'. There was a link, then I took it out. Hit the button again, same 
message. Then I took out all text that contained '[]', thinking that it 
was getting hung up by error messages from ros that contained brackets. 
That didn't solve anything.

I give up. ROS answers shouldn't be this hard to use...
