I usually visit this website on my phone and the chat doesn't work. I use safari. When I log into a computer I have a bunch of messages I never seen. Is there a different browser I can use on my phone so it works? Maybe someday we can get an app!
To use the 'chat' thingy you need to check the 'private chat' option in your 'preferences' section of your profile.
If you're having trouble getting the private chat thingy to work for you on a phone or tablet, theres an option to 'show private chatbar on mobile device' in the 'display prefs' bit of your 'preferences' section... Try that!
