I wonder how I can generate the online version of my newsletter with CM.
I post the answer:
There are instructions here http://help.campaignmonitor.com/topic.aspx?t=78 on creating a web version link.
This is something that's hosted by us and is unique to each subscriber (so activity is still tracked) It would be identical to the email version, so you couldn't have extra text or animations.
If you did want to have an extended version your best bet would be to create a separate version hosted on your clients website (or you own) and manually link to it rather than using the automated web version link.
