How do I find and 'complete' old questions?

Greetings, all!

I’ve asked a lot of questions on this board. I’m getting back into the groove, and want to know how to

-Find my old questions

-Give them the green border to complete them.

Click on your name. It will display your profile and all questions you’ve asked.

Thanks for being a good citizen!

I feel better now that all my old questions are completed. Yay!
