Hello Isaac,
Glad to hear from you. Here are some updates on organizing WPWP2021 in Bangla Wikipedia.
1. I've already formed a local organizing team of 10 members. We'll have a meeting tomorrow to discuss our strategies.
2. We've already started to make a list of the categories lacking photos.
3. Some of our editors are saying that getting a list using petscan tool will be onerous for our new editors. We've noticed that new editors often feel overwhelmed even learning MediaWiki syntaxes. So our fellow editors have suggested that we should give them a readymade list of articles lacking photos, they'll just search related photos in Wikimedia Commons and add them to the articles. We'll use bots to make the list of articles lacking photos which won't take more than some minutes.
4. We've also started to design our own Bangla WPWP2021 banner. We'll share it with everyone as soon as it gets done.
5. I think we should have some more specific and well-defined strategies for this event. Suppose we're targeting (1)totally new editors and (2)the editors who started editing Wikipedia, got no interest, and just left. We'll try to bring back those "boomerang editors" to Wikipedia. So we'll need to know how can we find those "boomerang editors", reach them, convince them, train them and grow their interest in Wikipedia. I think having some inter-cultural discussions can bring new ideas.
Best,
Rafi.
