I'd recommend "bumping" that thread (ie. just make a reply to it that says something to the effect of "I would like to see this fixed"). If that doesn't work, keep doing it every month.
As a developer myself, personally this system would drive me nuts ... but the P99 devs seem to not only be ok with it, they seem to actually like it (I once chided someone for bumping a bug and a couple hours later, as if to rebuke me, a staff member posted that it was fixed
