that's why I described the fact that foxmarks permit to use a own web space to store the data... (also because I doubt I would trust to store my chat logs on a centralized web space where everybody knows there are millions of chat logs..)
but implementing this feature/script would make possible other options I don't know, probably also commercial ones... up to you, as long as I can store them in another place.. XD
and naturally, I think there are ways to check if some data is allready stored exactly as the new one, so to cut down the redundancy of the sounds or gif images... just thinking a bit technically, dunno how complicated this would become..
anyway that was my idea, and I love it... cannot do more.. :/
