I thought that ShareCG would already know the IP address????? I have not given mine and I have had lots of trouble uploading since the beginning. BUT...I am in the UK and so many hoops have to be jumped. OR....did you mean the internet providers themselves????

I looked at the Renderosity postings and they confirm my experience. I cannot get my head around the fact that I download and upload to other US sites with no problem at all. Any help/suggestions would be welcome as I have had to give up uploading for now as it is far too time-consuming!...my only thought is the possible effect of security software?
