Adding website option for members in phpbb forum

I want the members of my forum to add their individual sites in their respective profiles(as like it is in myguestblog.com forum). How can i do that in phpbb?? And also, how can i verify their ownerships of the sites they will add in their profiles as like a security check (like meta verification, email verification or manual verification) to verify that they are the rightful owners of the sites?? Is it possible to do it with php??

 

This would be pretty involved addition to the default script options.
You may want to hire a programmer to do this for you.
If your interested in having me do it, send me a PM.

But i will try to answer the question best i can.
You need to add a new column in the database for the users website, and a php curl script that checks for a meta tag, or hidden file somewhere on the users site you ask him to upload.
The profile edit page will need to be edited for the new website field, the registration page will need to be edited for the new website field, and any where on the site you want the users website to appear will need to be edited. for example, under there user name each time they make a new post.
