Email Users and Generate a Mailing List for views/downloads of a specific thread

[perfphysio]

I would like to better communication with my members by filtering my email correspondance according to people who viewed a topic or downloaded a thread.

I already have "Who Viewed" and "Who Downloaded" mods installed and working fine. I can see their usernames which is great. However what I can't do is easily extra their email addresses.

It would be great in the admincp if we can generate an email list by either of those two options (either putting in a thread id or url for having downloaded or having viewed)

I am sure everyone would be stoked if someone could make this
