Tasks in Wrike' project management workspace now have a special tab called "Discussions" (1). There you can leave your comments (2) with images (3) and attachments (4) to the task and view messages of other team members (5).
When you update a task via email by adding [email protected] to the task recipients, Wrike intelligently identifies your comment (6) and adds it to task’s discussions (7).
All attachments to the comments are also visible from the "Files" tab (8). This lets you access important project information from both places.

How much does the useful upgrade cost you? Nothing! The feature is added to your subscription for free.
