Our Policy Board has also expressed an interest- in choosing future members, instead of having TAC members choose the new members as has been done in the past. As a result, we are changing the application process. The next Board meeting isn't until September (we're giving Board members a short summer break) so nothing will happen until at least then, when we receive direction on how to move forward in filling the position. And most likely we will seek multiple new members at that time, as two current member's terms expire in late 2012.
So for now my advice would be to check back here in September. I'll post more as soon as I know more. Or you can contact me at firstname.lastname@example.org with your name and contact information and I'll put you on a list to get ahold of directly when I have more information.
