Hi sorry about this, just testing that I'm still on this list as I have received any mail for a couple of days. I should have acknowledge on and copy to sender (or whatever its called) on so if I don't get a copy or two and I see it on the archive I guess I'll just have to re subscribe. Looking at the archive looks like I missed a couple of interesting threads. :-( ---------------------------------------------------------------------------- | Richard Thomas Computer Officer | | Department of Design, | | Brunel University, Runnymede, Egham, TW20 0JZ, UK. | | Richard.Thomas@brunel.ac.uk phone: 01784 431341 x267 | ----------------------------------------------------------------------------
