I'd like, on one hand, to simplify closure procedure from requester point of view and, on the other hand, to get feedback about how the request was done.

1. Is it possible to grant requester right to close resolved issue throught web interface?

2. If yes, how to ask requester to give measurable feedback about each issue which he closes?

in other words, I want to see following scenario

- IT staff resolve an issue

- Requester gets notification via mail and can goes to web form for details.

- There requester can accept the issue resolved and before status changes to "closed",  there is pop-up form where requester have to choose the satisfaction level.

Thank you
