I am continually finding it difficult/impossible to find certain messages I have previously sent; they seem to just disappear (i.e. they aren't in "sent", "all mail", or "trash." Regardless of that mystery, can you answer this: If I delete a message in a conversation thread, I assume all messages in that thread are deleted? By the same token, if I delete a message, does all the associated messages I sent also go in the trash (i.e. they get removed from the "Sent" folder")? I like GMail...but some of the ways it seems to handle message conversations/threads is sort of confusing (or, perhaps, I'm just a little dense). I'm thinking I probably need to stop using Delete and only use Archive because of this ongoing confusion.... Thanks for your clarification with this!
