They are finishing the assimilation today I think (it was meant to be finished on Friday but I guess they don't stick to that 1 week schedule too much). There is a guy at the school who was working with me for work experience who is staying on til summer term ends so there is someone there to guide them at least, although I heard yesterday that they built the new system on our library PCs which weren't meant to get it but no-ones complaining.
But from what I am hearing, the problems don't really start til the engineers leave...
