in order to get your skype account working under fring, u need to have skype already installed on your device. about your yahoo account, you just have tou put your username without "@yahoo....".
i have been using fring for a while and i believed in it until the day I recieved a mail from somebody working with the developers team(he should be the head of the team), telling me that they don't want to provide us an API nor anything that we could use in order to develop it on our plate form.
on another hand I can see other plateforme users such a java,symbians,iphone,WM... enjoying theirself with all the stuffs that fring provides them on its website.
anyway, I think that people don't give us any importance, and in case there really are developers in this community, you are the only one able to make things happening...
because nobody care abt uss.
otherwise, I can notice a kind of flash on the top of my device's camera., I have never seen it fonctioning I don't even know weither it works. why?----> nobody cares
