Maybe it's location somehow? I'm in the UK.
For example, refreshing the home page causes the background picture at the top to take several seconds to show up after a long delay of nothing happening. Other images literally load slowly, you can see them unfolding downwards. It's not just the pictures though, but the whole forum responsiveness that's sluggish.
Does this not happen when you browse the site?
Please note that I'm otherwise quite the fan of your site as I grew up in the 80s, hence can relate and would like to join. For example, this has to be one of the best tracks of the decade:
All the way from 1984 this synth track is one of the best ever. Here's the extended version. Oh and it was the theme tune to Beverley Hills Cop starring Eddie Murphy. It was played throughout the whole movie which made it simply epic.
