Lightning - Can't create new calendar

I installed the Lightning calendar extension in my Thunderbird to manage the numerous meeting requests I've been receiving lately and it didn't work right out of the box. It wasn't detecting meeting requests and I couldn't even see the calendar. After a bit of googleing I found at the bottom of this thread that in Ubuntu 7.10 Gusty Gibbons you need to install the libstdc++5 package.

I ran the command: sudo apt-get install libstdc++5

Uninstalled and reinstalled the lightening package and it worked.

Thunderbird - purge

I was trying to delete a fairly large number of emails from my Inbox in Thunderbird (using imap) and it was trying to move them Inbox.Trash. I don't normally mind this, but it wasn't working and I really don't want to keep the messages, if I delete something, I don't need a history of it. I found the setting in the accounts options to "mark message as deleted" but then I couldn't find an Expunge or Purge button or menu option anywhere. I googled it as I usually do and found that Thunderbird doesn't have a way of doing this other than setting it to expunge when shutting down Thunderbird. A little more digging and I found the Purge plugin:

https://addons.mozilla.org/en-US/thunderbird/addon/1792

I've added the "Purge" button to my toolbar and now when I delete a message, it crosses it out and when I click the "Purge" button it deletes the messages permanently.
