Change the link to my profile

Example.

On this site when you click on "My Profile" page, we get page www.joomlapolis.com/my-profile

But why did not I go to a page with its own unique address of the profile (as in any social network), because not every user will be able to understand how to create a link to a page with his profile. For example, you can not do that, but wants to send your CB page link to your friends.

How to make sure that when you click on My Profile, I got page www.joomlapolis.com/my-profile/userprofile/Allod

Hello,

you can use a content module and substitution
domain.tld/members/my-profile/userprofile/ [cb:userdata field="username" /]

with this module content all user can copy/paste his own link

Hope it helps
