Please read the rules.
To answer your question, the mobile version of the site doesn't show sidebars and certain features. Inconvenient, but a mobile API is coming and apps will follow. As for the tour, it's been disabled for the time being.
Thank you for your answers, this was very helpful. You say to read the rules though, I don't see a way I broke the rules so are you just saying that to make sure I did, or did I do something wrong?
Glad to help.
Questions in this tribe require a question mark in the title. It's a quirky rule, but try to remember next time.
