[Grammar] "She do" or "she does"?

[Xenon32]

Hi,
I see in a web site the conjugation of the verb do but I have a doubt, I know the third person of singular is conjugated 'She does' but they conjugate the verb as 'She do' calling this mode Conjuntive. Could you explain me if it is correct?

Thanks,

The subjunctive mood is sometimes called the conjunctive mood, as in I insist that she do her homework on her own, without your help.
