Email Copies, Redirect Topics and Announcement Ideas

First off, thank you for making a great forum package. I love the speed and understand how keeping things lightweight is important, I can't wait for 1.4, it's exciting to follow the progress in trac. After using it for 3 years I really don't have many complaints, however I hope you won't mind me sharing a few ideas for your consideration.

1. I think a 'send a copy to my address' check box would be useful on the send email form page.

2. If you merge 2 threads and leave a redirect topic, the redirect sends you to the first post of the oldest thread. I realize this makes sense logistically, but often it would be useful to have it link directly to the first post of the newer thread.

For example: Someone makes a new thread: "How do you pitch a tent", ignoring the "All camping questions go here" thread. If you merged them and decided to leave a redirect topic for that person, it would be useful if the redirect topic linked to the "How do you pitch a tent" post within the older camping questions thread. Do you think  an option to do this would be possible or justifiable?

3. I modified the announcement code using these instructions, so the announcement message only appears for guests. I think it's useful to be able to display a message to guests, and considering that a message for guests will typically always be displayed while an announcement for registered members is used less frequently, one could make the case for this as the default behavior. I think it would be great to have both as an option.

Thanks for your consideration!
