Hi,
First of all, my apology for my email in english.
It would be great to send an experienced photographer to cover the Hajj 2018 (or 2019).
There is a lot of pictures of the Hajj on Wikimedia Commons [1] but almost nothing of quality.
I would be happy to work on this project. I can elaborate the budget, find some funds for the project (I think that some European chapters would be happy to fund that), obtain a media accreditation, etc.. The number of accreditations is very limited and Saudi Arabia probably censored a lot of articles of Wikipedia, but let's try! Some wikimedians send Wikipedia on the Moon [2], we could try to send someone to Mecca ;)
