Student or Learner
Is the use of the Present Perfect correct in this case?:
(A and B meet for the first time).
A says to B: Nice to meet you, your brother has told me much about you.
(The tense is correct, but there's a comma splice. You need to make that two sentences.)
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
