This one's been a long time coming. You can now attach files to comments in TeamworkPM.
We spent a lot of time making this feature easy to use and it works just like it does when attaching files to messages and tasks. You can even attach files directly from your company Dropbox account! We are happy with the interface and we hope you are going to love it too.
The new comment attachments look like this:
Posting comments via email will support file attachments in the coming days (Dan is locked in his office with the music turned up beavering away on this).
We hope you are all going to love this feature and that it will help you stay productive.
Thanks again for using TeamworkPM!
UPDATE
As promised above, when posting comments via email, email attachments are now attached to the comment.
