It does depend on the browser that you use. You can click on Community in the first blue bar. The drop down will show air forums number. Click on that. It will take you to a directory lookup which will get you to your member name. Once you find it in the listings you will see your air forums number.
Using that way I found your number. 82966
I'm using Safari on a mac and if I click on hold on the user name, I have to drag the curser down slightly to see a box that has an http address with the number to the far right within the address.
