1.When a user makes a lend request from the website, the final message says something like - thanks for the lend request, we'll get back to you. But on our end, when we "approve the request" there is no email sent to the user ?
In book library you has option in BookLibrary setting - for send or not to user reply with Rent request solution.
2. If a member wants to renew, they send in another Lend Request. So what steps should we take?
He may do exactly as for first rent request, or connect witj admin with help contact form or some other.
And admin may edit current user RENT for that books, As example admin may set other date.
