See 1 minute movie:
its easy to set up/create your own skin and seems to work well although there is a few things that need sorting.
the chatters replies text colour cant be changed from black even when set to another colour, the log in text also cant be changed which limits background choices where you type.
the amount of time the chat text stays visable should be made longer too as quite often it disapears leaving a empty chat box, atleast keep it for 24h even just whats on view without scrolling.
im sure these things will be changed
even so i would recomend using this chat either as free or a upgrade as it is very good,the best ive used so far
