Marcia,
What might a person have done - or not done - if the invite list
still says "Sent" instead of "Accepted" and she has posted a couple
emails to the group. She thinks she accepted.
Could she have more than one email address? One still "Sent" and another that posted to the group?
Or does the group allow posting by non-members?
Otherwise I'm at a loss for how she posted to the group before accepting the invitation, or how she would think she has but the site thinks otherwise.
The other half of the coin is whether she's receiving postings from the group. That even more so should not happen until after she accepts the invite.
Is there a way I can change Sent to Accepted?
I don't think you can, it should be strictly up to her. If you could that would be tantamount to a Direct Add. Which is something only a Premium or Enterprise group should have.
