I think "o' clock" is only used by 12 hour time, not sure. It does make sense since a clock does not have more than 12 divisions, and the origin of the phrase obviously involves a clock :o
From what I understand, "o' clock" can be used with either time system, but "Hundred hours" is for military time, which uses the 24-hour system, but not all 24-hour systems are military time. (Run-on sentence?) Kind of like the square-rectangle relationship, or something.
I think you are though, since you are one of the members I totally respect, appreciate, etc. from afar, but most people (here) that think they are mature are just naive. Unless, you're just trying to say we're mature compared to four-years olds, then that's true.
The flag comment is actually a neat suggestion. :)
About the PM search, the mods can only look at PMs if someone reported it, like giving them permission; if someone abuses the report, it's them who'll be punished and etc., etc.
I don't want to double post so I'll just say it here too, I see many people biching about bans, I say:
SavageWolf = / = Pseudolonewolf
I would say more but I already got my main point across.
