Please tell me how Whatsapp Inc. pay the big servers thay have and the salaries. Facebook privacy policy is quite better than Whatsapp one. But don't worry, mainly I use Google+.

I thought that Wazzap makes a synchronization when you run it first time (and maybe every time you run it) and the sync button is for resyncing it. Wazzap do not automatically sync if you don't touch the sync button?

Thank you for the sugestion but then I would prefer to use Yappari.

If Wazzap only makes synchronization of numbers with international prefix (and not all) I will be happy too, because I will only need to add the prefix to the contacts I want in Wazzap. Please tell me about it.

@don_falcone:

I like your signature, but even friends that like free software didn't want to hear me . So I will try to use my google-talk account (where I have all my contacts from google-talk, facebook and msn through the use of transports) whenever is possible but most people only uses Whatsfack.
