I use Thunderbird with a gmail account. I want to work on my local TB email....and use the gmail account only for the server. I have two questions re keeping the emails in synch. 1) In thunderbird, I delete emails I don't want. How do I automatically have these deleted from the gmail account I use IMAP. 2) I want to store my archive in local folders in thunderbird on my local laptop. How can I automatically have the emails I move to local folders delete from the gmail server? Thanks in advance. Rick

For the last couple weeks thunderbird is very slow....ie typing a new email typing can take a couple seconds to appear on the screen. I don't recall any changes I have made, other than deleting many old messages and filing many messages in local Thunderbird folders.
