We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Remove fixed subject line from contact form
The contact form has a drop down for choosing a topic. When patrons submit this form, the submissions all go to the same inbox. The selected topics are usually incorrect, but also make it more difficult to manage the inbox due to most messages looking the same.

### Describe the problem that you'd like solved
Let the patron populate the subject line OR auto-populate the subject line from the message.

### Proposal & Constraints
<!-- What is the proposed solution / implementation? Is there a precedent of this approach succeeding elsewhere? -->

<!-- Which suggestions or requirements should be considered for how feature needs to appear or be implemented? -->

### Additional context
<!-- Add any other context or screenshots about the feature request here. -->

### Stakeholders
<!-- @ tag stakeholders of this bug -->
