You mean the “repro” tag?
From the forum newbie’s point of view:
- It’s small and hard to notice. It’s not as visible as for example a separate “I confirmed the bug and the developers were informed. Thank you!” message from moderators.
- It’s hard to know what it means and who added it.
- It is even harder to understand that that’s where the moderators would make any changes; that the bug reporter should look among the tags he filled in to see any new changes that should represent the change in bug report’s status. This is very non-trivial logic.
