I trust Howard's word implicitly. As he said, he has no dog in this fight. We have encountered a number of weirdness with vBulletin. Multiple E-Mails, changing stuff that stays the same (no, not the thanks hack) as well as many other things. We have had to tweak this software to work with the load we have on it. Tweaks can affect things without any reason, but hopefully not too much. If it negatively affects a large portion of the board then we work diligently to correct it.
But, as I pointed out, things seem to be working here. I just looked at the settings and they all seem to be in order. This only seems to be affecting the KOH, and I agree with Howard: there is no conspiracy among staff to annoy this small group. I must say that I find it mildly amusing that this group (with it's history of causing several melt downs) is accusing us of some sort of collusion against them. It's ironic, doncha think?
I have no reason to not trust Howard - he has been helpful.
There remains a dispute of the facts - so one possibility is that although the Thanks hack is unchanged, some other "tweak" has altered its functionality.
I have seen no accusation of collusion - this could easily be the work of a lone individual. Perhaps even an unintended consequence.
