The link u gave was useful but for that i first to need to host my website on net. So it will check the email addresses validity. I have gone through a tutorial in which the email addresses do not exist in real world but are created using a smtp server in which we can check them.
As the previous post said about private messaging system im planning to construct something similar in this forum. Like we can send privete messages to the users. I ve already given each user a username, passord, id. How can a module of this type be constructed. Can you give me a guideline for this.
Plz help me.
