We're a team of five (two work remotely) at Citybot -- Lechat works very well for us. History is always there, no ridiculous kissing smiley faces (hello Skype), no ridiculous out of sync notifications that are months old (hello Skype). We've been beta testing it for about a month and it's been making our lives easier and communication clearer. The support is right on. The speed with which the Lechat team adds useful features is phenomenal. Never at expense of quality. Would love to see the native clients, and they say they're coming soon. I absolutely totally recommend it. Try it out!
