Can we say
I forgot meeting him before.
I remember to have met him before. ??
A.J. Thomson & A.V. Martinet say in their A PRACTICAL ENGLISH GRAMMAR that we don't use forget doing sth in an affirmative sentence. Is that so? And can remember followed by to have done sth?
It's possible to use the affirmative. I wouldn't use 'remember to have met'
