Ok I found out that online NDA doesnt exists but how can I protect myself since I really dont want to send all those papers through mail ... Does some sort of online contract or does PMs, mails, etc. count as evidece if it comes to stealing of some sort ... Thank you for your answers.
NDA wont stand much over the internet. Digitally signed certificates can be used as evidence, but overall there is no security.
Non-disclosure agreement You can read more about it here: hxxp://en.wikipedia.org/wiki/Non-disclosure_agreement (wiki) Sorry I thought I write it what it stands for ... I will get a sample soon and will post it here
