Fix email thread joining!
I have several occurrences where two different threads from two different contact are being joined together. It's very inconvenient to have to sift through the email thread to gleam information regarding one conversation then make sure to reply to the correct individual without compromising the conversation with the other individual. Why is yahoo mail doing this? the two different individuals have nothing to do with each other and they have two very different email addresses. They should not be lumped together into one thread. They should remain separate.
