I don't see a problem with posting the Wanted Ad on the Groundspeak forum. There seems to be so few people using it, that even if you need nudge the etiquette or bend any rules a smidgen, I don't think anyone is really going to mind. It could do with a few posts to breath a bit of life into it.

Maybe you could post your Wanted Ad here on this forum and then get GG to tweet the thread, and do a 'forum mail all'? That should bring attention to your wants from some of the right places.
