Under the project Wiki Documents Bengal Terracotta, the West Bengal Wikimedians User Group has been documenting the intricate terracotta panels of temples in South Asia.

They are combining the efforts of photographers and researchers. Get inspired by their clever solutions ➡️ w.wiki/FnNW
A series of weathered terracotta plaques forming an external wall panel of a historic temple in Bengal. The bricks are carved with detailed reliefs showing human and animal figures arranged in horizontal rows — the motifs evoke mythological, religious or folkloric scenes typical of Bengal’s terracotta tradition. The overall tone is earthy-brown, with visible wear and age that hint at the monument’s antiquity. Text reads: Discovering the Bengal Terracotta history by connecting researches to Wikimedia Commons

Risker corrected a typo in singer James Blunt's article nearly two decades ago. This inspired her to become one of English Wikipedia’s most trusted leaders: administrator, arbitrator, and checkuser. Her journey from fixing a typo to guiding global policy shows small actions can lead to big impact.

"Don’t stick to doing just one thing. There are so many different things to do. A very common reason for editor burnout is excessive focus on one task."

Integrity is built, not assumed. Wikipedia’s standards can inspire how we share and consume information online. Wikipedia’s collaborative model matters: through discussion, edits, and consensus-building, neutrality is something achieved collectively.
