I currently use IMO.im, which is great except they don't offer group chat... I'm looking for something similiar but with that feature.
- Group chat (like a desktop app)
- Web based (no desktop apps!)
- Support gTalk/Aim/Msn/Skype
Nice to have:
- Chrome plugin
- "off the record" type feature
Edit: Sorry I should have mentioned that I'm absolutely fed up with Gmails built in chat - if I receive one more "Soandso hasn't received your message" notification, I might jump off a cliff. (The worst part is that we tested it in office, and sometimes people DO get the messages, and it still shows the error). Also I need MSN/Skype.
The group chat doesn't have to work accross protocols. Just needs to support group chat for the individual protocols. (In other words I don't need to invite Skype contacts to a Google Talk group chat).
