[chirp_devel] How to close the issue?

I would like to ask how to close an existing task? For example this: http://chirp.danplanet.com/issues/2033 I created it, I solved it, I can change her willingness to 100% or who can do? What are the conditions required to close the task? The question has arisen due to the fact that if you go to the list of problems: http://chirp.danplanet.com/projects/chirp/issues in the list of tasks is open and if it look in more detail, it is already sealed. I'm through trying to help open tasks as a programmer project CHIRP, but I do not want to sort the entire list, and try not to find the solution.
