Right please don't take this as a personal attack lol... This is for information of everyone not just you mate, a lot of people have asked simular Q's so its time for an answer.. Ill start at the last bit of your post... apps like this will only be effective if you got internet :D Chat: Hardly anyone uses public chat rooms with multiple members active in the same room anymore, only chats used now are 1 on 1 ones like facebook, MSN messenger ect.. our PM system is sufficient enough for this. Notifications: I persume you mean notifications straight to your mobile? Anyway, what I do, in threads that I want to keep track of, I subscribe to that thread, when it is posted upon, I get an email, my phone instantly recieves emails..I know there is a new post!! Inbox's: Our PM system?
