Just want to throw in my 2 cents here.
It's clear from this thread (and others) that some posters just don't like being moderated. To openly question moderator decisions on-thread has never been allowed in the NUIG forum (or anywhere on Boards) in my time here, yet I've seen time and time again, multiple posters from this thread do it since the current mods were appointed. Frankly I'm surprised they didn't ban people for it, despite multiple warnings on the subject and it being in the charter (iirc I was the one who put it there months ago, if not it was one of the mods before me). There's a reason it's kept to PM and the Helpdesk so that the thread doesn't get derailed and end up a mess.
To say that the "economics" discussion was relevant to NUIG was a stretch. It started out as a bitch on why two vending machines had different prices and developed into quips about anti-Semitism...in what world would any good of come of that, especially when someone began calling people anti-Semitics (i think that post has since been deleted). That wasn't discussion, that was a flame-war waiting to happen, and it did happen to an extent with one or two posters hurling abuse.
Saying that the mods want to "flaunt" their authority, do ye really think they want to put extra work on themselves by dealing with the fallout of bans and infractions? Modding is no easy task, and I don't envy KittyeeTrix or musical.x for doing it, as I know first-hand how challenging it can be.
Regarding the "Titrations" and "Applied Maths exam" threads, homework threads generally go unanswered in the NUIG forum, given that it's not a particularly busy forum compared to the other college fora and are best redirected to the relevant forum, where they usually get answered quicker and better. I offered help to MannyFagnet (the OP for the Applied Maths thread) by way of PM if he wanted it, but given he hasn't been online since he started an identical thread in the Maths forum at the same time, I think it's a non-issue that Kittyee locked that thread. If he had any problems with it, he could have PM'd her to re-open it.
Ficheall, the "mod-free" period Bobblehead is referring to is when brianthebard went AWOL in May last year (here's hoping all's well with him btw) to the point where I was appointed mod in November last year. Brian was listed as mod, but in essence NUIG had no mod for that time.
TL;DR: Some of the posters here think they can challenge mod comments and actions on-thread (which has never been allowed on boards afaik) and get away with it, given that from what I've seen, the mods don't seem to take tough enough action on these posts.
Rather than point blame at the mods, why not look at your own posting styles and see if they could be improved so that you don't need mod action? They don't do it for the lulz.
