Impossibility to use Ping project on projects over 50 participants
Closed, DeclinedPublic


When trying to ping 3 different projects on a property proposal (about copyright), I discovered that it was impossible, because 2 of those 3 projects have over 50 participants (Books and sum of all paintings).

This is specifically problematic because it concerns succesfull projects, because most participants will never be conscious of this limit, and the notifications will never be done, while the message "project participants notified" is displayed, thus leading to very bad dialog on big projects and it is also very difficult to notify everybody individually.

It would be nice if the upper limit of 50 was removed when ping is made using {{ping project}}, especially when the user adding it is member of the project. This limit makes this template useless precisely where it would be the most useful.

Originally, the limit was 300. That was then reduced to 100, and then to 20. The limit of 20 has been getting regular complaints, so they're raising it to 50. Suggestions/alternatives welcome. :)

{{Ping project}} uses a Hidden Structure which causes issues for bots, web scrapers, and screen readers. The proper fix is to add the functionality to Echo.

I really don't think Echo Notifications are the right solution to this problem. If you need to message more than 50 people at once, you should probably use a mailing list. There's also the Newsletter extension, which is installed on and could be installed on Wikidata as well. If neither of those solutions will work, I think we may need to create some new software specifically to address this use case (that is separate from mention notifications). The fact that {{ping project}} uses hidden content is also problematic. Rather than expanding this hack, maybe we need something different.

Regardless, when we had higher ping thresholds before, we got lots of complaints about misuse. The current 50 person threshold is a compromise that was reached over a long period of trial and error and I don't think significantly changing it is a good idea.

The problem is to ping the members of a specific project on wikidata, for discussions outside the project, (on property discussion, on the project chat, etc.), because all members of the project are potentially concerned by the discussion.
A mailing list or a newsletter would be no use at all for this purpose.

I don't understand at all how 'ping project' template works : I only see that it becomes useless precisely when it would the most useful :(

@Hsarrazin: Typically on other wikis, the way to notify a project of a discussion is to post on the project's talk page.

We are considering this for Growth team maintenance work.

@JTannerWMF -- this task is supposed to be in our "Revisit" column, but I can't figure out how to get it there. Could you please help?

[offtopic:] @MMiller_WMF: Clicking in the upper right corner of and then " Manage Workboard" and then "Revisit", you can see that the "Revisit" column was hidden:

@Aklapper - Somehow this task is in 2 different columns on the same board simultaneously. I can't find any mechanism to remove a task from a column, but not a workboard. Any advice?

@kaldari: Workboard visualization out of sync, I guess... I tried to drag it from "Revisit" to the "Upcoming Work" column and got Unhandled Exception: Unable to find object "PHID-TASK-bqrlttxcm5qknkucjucy" in column "PHID-PCOL-vaw55qipj2ivbyj6koqk" on board "PHID-PROJ-m5xekuzpcucwdjim2onx. Dragging the other way round (from Upcoming to Revisit) and then back (from Revisit to Upcoming) removed the duplicate. Feel free to file a bug report under Phabricator.

We have decided to decline this task after discussing on our team. The reason is that this pinging limit has been the subject of debate for a while, and has moved around over time -- it has been up to 300 and as low as 20. The limit is there for good reasons, and the workarounds that exist seem to do a good job of helping make sure that people who really need to ping many users can do it. For the specific "ping project" use-case, we recommend that the bot behind the template be modified to ping people in batches of 50.
