owh that is strange...but i guess each site has its own instructions...so, probably Gmail has gotten kinda of such stuff...ok, try to add this person in another account, or u only have gmail account?
i mean why dont u try to sign in another account at yahoo or hotmail if u really need the address of that person..or just ask him or her to do another account that is formed in a simple shape without compication...
