Well that's what confused me, I didn't read it anywhere but jQuery just 
seems to do it as a matter of course so I inferred it must be standard 
practice in the world of AJAX.

Aah, that makes total sense now, thanks :)

Well this bit is quite simple but it's all part of a bigger suite of 
tools I'm working on so I figure it wouldn't hurt to stay with the 
program and document/test the living bejesus out of it.

Thanks for the advice, that's a good rule of thumb although one should 
always bear in mind Einstein's slightly longer version: "Make everything 
as simple as possible, but not simpler". Part of the reason I started 
the project I'm working on now is to try and overcome the shortcomings 
of other lightweight CRM systems which started off with too simplistic a 
database schema and too little separation between M, V and C.

Cheers,

Roger
