Ouch, Rob.
Umm, hardly.
And no, asking won't do anything.
At present we are on our third wave of moderators. They had moderators once upon a time, then a period of none, then there was an enormous influx of new members which generated a call for moderators again. Many of those moderators asked to step down or had less opportunity to visit the site so the site owner, Rob_E, created a thread for applicants who were interested. The current group were selected from those applicants.
From the most recent group we have had three step down. I don't know if Rob intends to keep the current number, expand or decrease or even eliminate the moderators entirely. If there is a call for more moderators Rob_E will likely either contact those he feels would be good for the site or he will have another application thread.
Please don't send the mods PMs asking for the position, it isn't our call. And I daresay flooding Rob_E with requests will thrill him. It wouldn't thrill me.
