Most forums, by default, would auto-subscribe you to your own postings/threads... this one does not.

I added a check to the auto-subscribe option in my User Options and now when I click the "My Subscription" button, my subscribed threads appearat the bottom of all those forum checkbox options. Be nicer if my threads came before all those checkboxes... is there another place to view em? It's a tad clunky, but OK I guess.
