Hello bornabirth! Thank you for dropping a line. I am expecting a very good advice from you. Thanks anyway.
Yes, I am selling my book online and in person as well if only to answer your first question. But I did not post a thread bec of that reason. I am referring to the security/protection so on and so forth in giving out details online. This is not just about merely selling/buying. This is also to do with enquiries of a lot of things online which one is requred to give out details such as phone numbers, address, etc to someone who is just behind the PC.
