Some forums have the option for moderators to go back and change thread titles.
I've seen this forum has a "thread blending" option. Perhaps a moderator (such as yourself?) could start a thread called "pupdate" and then merge this thread into it.
by going back and deleting your own first post in the "pupdate" thread, it would leave these posts under the thread title "pupdate!"
Man, that's a whole lotta work. Screw it.
