socialtalks gives the path to the users to keep communication online.After it asks to connect to Facebook, in fact, the only way to sign in to the socialtalk app is via Facebook. You will also want to pay attention to what Path can access in Facebook because it pretty much wants to access every single thing on your profile.
Once you sign in Path queries your Facebook friends and presents a list of five that it thinks are your most active friends, although I am skeptical of that list because one of my friends it presented hardly ever signs on to Facebook. You do have the option to invite additional people either from your Facebook friends or via an e-mail address you provide, though you are limited to fifty.

is this free of cost ?
