Well... now I know some of the reason the forums are so slow.
I'd know more if I could speak spanish, but a lot of the coding is the same regardless of language.
The site is loading ALL of the functions on every page load. Even when it's not needed. You don't need to verify age/other details EXCEPT on the page where they user is actually putting them in. If you've coded things right, your user can't be logged in without those things being verified. Loading all of those functions adds precious seconds to load time.
They are using an .htc file to make .PNG files work in IE 5. Admirable, except that anyone who is still using IE 5 is going to be on such an ancient piece of crap they're going to have ridiculous problems anyways (a machine that can't run the latest IE is going to take several minutes to load and display just ONE of these pages). A MUCH simpler solution would have been to just just .gif or .jpg images throughout. Sure there's a few fancy things you can do with .png files, but not enough to warrent saddling the majority of your users with extra load times.
As far as them reading the forums, remember it's all coded in Spanish, or some other crazy moon language I can't read, so chances are even if they do read the forums, they don't understand what we're saying.
