HOWTO Mark you thread as [SOLVED]

Some helpful person on the Ubuntu forums has just solved that issue that has been causing you to tear your hair out. You want to proclaim to the world that everything is now peachy, but you're not sure how and you don't want to embarass yourself on the forums by declairing your undying love for the aforementioned resolver. Well there is a simple way. Find your thread, and at the top, click on the "Thread Tools" button. A small menu will pop up, and at the bottom there is a "Mark this thread as solved" option. Click on this, and a nice [SOLVED] text will appear in the title of your thread.

Now this has a twofold use;

1. It lets the person who answered your thread that everything is working

2. It lets other people searching the forums know that this thread provides a working solution (at least to the original poster) for their problem
