When users file suggestions for new collections, they want to be able to track the progress of that request as we go through our pipeline for trying to get a partnership with them. We could build a flexible progress and updates system into the library, but this seems like a potentially substantial project.
Instead, we created a Phabricator board at https://phabricator.wikimedia.org/project/view/4808/. Phabricator already has functionality for commenting, writing descriptions, and moving tickets across a board to show progress.
Now all we need is a way to link the suggestions to a Phabricator ticket, so that users who visit the suggestion page can click through to see what the progress on that request is.
We can add a new field to Suggestion objects for the Phabricator ticket number, and then link the URL in the suggestion interface. This could be displayed as a new line below 'Proposer' which says 'Track progress' and links to the Phabricator ticket URL.
