Add Join Form to login page

Trying to figure out what would I have to do so have some of the fields in the join form on the login page instead of being redirected for users having to complete the entire form.

Can anybody help me with this?

anybody know how?

No such page named login page. Be more specific.

Do you mean a custom splash page?

If you mean the index also known as the home page, then there is a free mod in the market to do that. http://www.boonex.com/m/Site_s_Join

Yes, that's what I meant. Thank you very much. 

Wrong terminology can be a roadblock to getting help.
