I sometimes miss “public service announcements” on here so i used http://ifttt.com to monitor the forum feed and post whenever someone mentions “P S A” (without the spaces, or this post/thread will clog it up a bit)
slightly annoyingly it will re-post when people comment in a thread, so how useful it will actually be as an easily browsed archive will remain to be seen – there’s not an rss feed for first posts only unfortunately, that i could see.

tumblr: http://stwpsa.tumblr.com
They will fill up over time from now.
With http://ifttt.com you can do similar keyword monitors and set it to email you immediately when they come up btw, which is particularly useful when waiting for something specific in the classifieds..
