Hmmm.. cheers for the replies guys. Mistcaller - what I meant was the settings that determine the distance between objects (either placeables etc. or PCs) can go before they are 'bounced' apart. I'm certain it can be changed. I heard from someone else about it & did a search on it. The few references I found weren't much help, till I came across a PW which used it (scrabbles around in his history folder for a moment) - one called 'Duchy of Genoa' (it's a social PW by the looks of it - with zero magic!, not my thing, but looks to have had a lot of hours spent building it). They used it to allow PCs to get 'personal'

. Seems they're going down the pan at the moment though. I kind of felt sorry for 'em actually, and borrowed a part of a post from Orl (hope he doesn't mind, it was from the public forum - and I removed all names) giving some excellent advice on 'promoting your PW' - seeing as how they're not exactly competitors of Avlis.
As an aside, it seems they have someone pretty hot at scripting/coding there, who may well be available if things get much worse for them.
The only other reference I could find was for a completely defunct PW.
Trust me to get an idea stuck in my head about doing something on the fringes of the NWN engine, when I've only started digging into scripting for about a month or so! OTOH I've been an analyst/programmer all my career, so old habits etc.
/edit: damn, I spelt it 'Dutchy' the first time...
