Hi
At the moment when you registered new lead you have only one opportunity "remove".
But maybe on future can add opportunity "Edit" lead.
Because today I have situation when I create new lead and in field "Lead Value"
I entered 588.68 after lead registration finished in leads list shows value 58868.00!
So I had no opportunity to correct this lead so I remove it.
After that when I start create new lead I have problem registered lead because I received
Error "Lead with this number already exist", so I need to correct Company VAT number.
Best regards
