I am looking for a instant messaging system which:
1. has an attractive realtime chat UI
2. has mobile apps (iOS/Android) so that users can also reply via mobile
3. allows to respond to messages by email in case the receiver is not online on website. It should also update the messages & attachments sent via emails to message thread on website
4. can also be integrated with Joomla website in some way (not a compulsion)
Send me your detailed proposals with flow / demo.
PLS READ THE PROJECT DESCRIPTION BEFORE APPLYING. FIRST WORD OF YOUR PROPOSAL SHOULD BE 'HELLO M SYSTEM'. (just to make sure you went through above details)
