We don't have a seperate WAP-compliant server. However, one way to expedite surfing from a mobile device is to go to User CP then click Edit Options, then uncheck "Show Signatures", "Show Avatars", and "Show Images". Navigation will be faster.
My sidekick and my blackberry both pull up Martialtalk just fine. It does load up slowly and there is a delay with posting my comments. Javascript makes it go snail-pace, so I disable that feature. If speed is not your top priority... Check on what options your mobile device's browser offers and turn off whatever you can live without. Of course, I prefer good ol' computer.
Just curious what kind of mobile device do you have?
It's stripped down, but looses a lot of the useful stuff. New post search, ability to post, etc. But for just browsing its a option, there is even a PDA version and login ability.
