Let's remember that the mods volunteer their time and (hopefully) have productive lives outside of these forums. As a long time member, I can count on my hands the number of times a problem has taken more than an hour or so to resolve. Pretty damn good in my opinion.
And like the rest of us, mods sometimes need a break from this place which may cause coverage to be a bit less.
That said, the mods do a great job and I wouldn't want their job at twice the pay.
