Well another thing to consider is this, some who release mods here don't speak English as a first language HOWEVER that does not mean they can't code like lightning in a bottle! That does mean that you may not find a in-depth guide or manual though however sometimes you can it's just dependent on the coder and where else he participates in a community i.e. vBulletin-Germany etc (You could find a more in-depth guide in their native tongue for example).
Also Christeris... this is a community however there's only pretty much two very simple requirements which are 1) Licensed vBulletin Owner 2) Account verified here so you can participate. So truly they can come here and never post in fact I bet my bottom dollar we have avid users who download and mark as installed that have never posted, if they don't have a problem then why post and if they have anything else in life to tend to then that's their excuse for not posting imo. I also try not to speak out at times just like you fmgrowit as many misconstrue that for being unprofessional by stating so when they tend to forget and look in the mirror although I go by my favorite quote:
"Sometimes you must speak out even if others don't want to hear it, otherwise your not being true to yourself"
So it seems you and Christeris did the exact same thing... so did I therefor we're not that different it's just that we always don't see eye to eye
