Help with member login/profile

I have a final question if I may Itai,

When a member clicks on My Profile, the link of the navigation shows member ID.
How can I manipulate the code to make it show Name instead?

For example:
This is what it shows:

/Profile/Members/e9adfe10-69bf-44ca-9b2b-c72fad4d3e91

Instead, I want it to show:

/Profile/Members/NameOfMember

Thank you so much for your help and time !
