What tables are updated?

[helpdivya]

I have a default field on my registration page that comes with SMF forum installtion. I would like to know what tables are updated when a user register on forum?

Mainly _members and _themes tables are updated. Also, "totalMembers" in _settings table is updated when a user registers completely. You can check the registerMember() function in Subs-Members.php file if you like.
