[SOLVED] How to mark a thread I posted as SOLVED ?

view story

http://ubuntuforums.org – I am still getting used to the new look of the forum , which I must add is quite nice. But I noticed that in the "thread tools" drop down menu , there is no 'Mark As Solved' . Does that option no longer exist ? If so , what procedure should I follow to indicate that my query is solved ? Do I simply post a reply to the thread ? Edit :- Oops , terribly sorry I saw there is a sticky thread for the same.
