I don't understand why so many people need to be so nasty here instead of trying to help. I think a text-only version or something similar for low-bandwidth users is a great idea, similar to what the English Amiga Board has just implemented with the "Mobile" version.
I must admit, I haven't used my Amiga online yet so I don't know how much trouble it would be, but I use this site from a PC with dialup and have no problems with it, so I don't think it's a speed related problem.
I hope you find a way around the problem and can post from your A4000 soon.
