Hi
Sorry about the delay in responding.
We do this all the time.
One way is just to have a simple large text field, and have people adding to it. However, this relies on them not modifying the content that went previously, and also correctly recording their id and the date, etc.
We have built a component called Task History, which will automatically insert comments, date, time and user into a repeating area of a form, effectively recording a full audit trail of everyone who's touched the form.
Unfortunately, the documentation is a bit sparse at the moment, but you can see it here:

I'll try to get the docs updated asap, as well as some samples.
