Gmail

[Gmail] is great but it can be better. Here or some more ideas to make gmail the best e-mail service on the web.

Gmail WikiMail
Have a e-mail that can have the option of [Wiki], so when you reply back and forth it doesnt look like a natural conversation, instead it's just one e-mail page being constantly changed back and forth. This would be good for group collaboration over gmail. So when a user starts to compose an e-mail they have the option of it being a Wiki mail. With this option selected the Recipients of the e-mail are then able to change it and can send it back to everyone for them to edit. It will not start a new reply window, just an editable e-mail. Each e-mail address could be a color, just like the conversations are. When users edit it, they just send it back to everyone.

Error Correction
If gmail user A is logged in and gmail registers that it is saving draft's of the wiki, it let's any other gmail users who have the same wiki sent to them, know that it is being edited so they dont do more work then they need to.

Gmail and Google Notebook Integration
Have a google e-mail that can be sent to google notebook. Often times I store notes or ideas in gmail as a saved draft,or send it to myself. Having this e-mail be sent to Google Notebook and my sent folder would help with information publication.
