I just want to share that I have experienced weird acrivity on my msn account after logging in once with Nimbuzz. Changed the password, removed nimbuzz. I don't know if it was deliberate hijacking of my account, a security hole or just a coincidence but be wary (after all, how do they make money?)
My point was you merely wrote a .desktop file, provided icon and wrote a few line guide and you are writing as if you developed or ported the app. You can take credit for writing a guide but not bny preteding that you ported the app or have you done some tweaking/reverse engineering with the nimbuzz.jar?
