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. :)

+1 This is urgently needed.

{{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 Mediawiki.org 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 https://phabricator.wikimedia.org/tag/growth-team/ and then " Manage Workboard" and then "Revisit", you can see that the "Revisit" column was hidden: https://phabricator.wikimedia.org/project/board/1114/column/12067/

@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.

Most of the issues listed in that task can be solved by solving the following tasks:

• T190250: Provide a way to notify groups of users
• T148154: Develop a properly-designed way to tag groups of users
• T108293: Echo should warn users who tries to mention more than 50 other users that they won't be notified
