WLM-VE is interested to send a personalized message (in Wikimedia Commons) to participants of WLE (2016), Wikiviajes (2014) and WLM (2013) for Venezuela's campaigns.
**Steps**
[ ] Get a list of all uploaders, which can be done with the '[[ http://tools.wmflabs.org/ptools/uploadersincat.php | Uploaders in cat ]]' tool. There might be a better tool out there, too. Example: [[ http://tools.wmflabs.org/ptools/uploadersincat.php?category=Images+from+Wiki+Loves+Monuments+2013+in+Venezuela | List of all uploaders for WLM-VE 2013 ]]
[ ] On the Commons, make a list of all uploaders' talk pages; each listing should be formatted like # {{#target:User talk:USERNAME}} ([[ https://commons.wikimedia.org/wiki/Commons:Wiki_Loves_Monuments_2017_in_the_United_States/Messages/Invitation_to_2016_participants/Recipients | see example ]])
[ ] Draft the message you want to send on a new page. Do not include a header, as the MassMessage tool has a separate field for that.
Ask an admin on the Commons to send the message out; I usually just post to the Admins' Noticeboard. See [[ https://commons.wikimedia.org/w/index.php?title=Commons%3AAdministrators%27_noticeboard&type=revision&diff=257068493&oldid=257038311 | my example request ]] on how to easily lay it out for admins. You basically want to provide the message, the header, and the list of user talk pages.
