Hi Romain, for the grade change, you would have to get in touch with us at [email protected]. These changes are always manual work for us, and they take a bit of time, but currently that is the only way to do it. However, if others log the same route and suggest a different grade, it will become the grade on the route info page, since we periodically update the grades on the route info to the consensus. For the spelling, you can use the 'report spelling' feature. You find the button on the top right of the route info page. Hope this helps.
Thanks Ben!
Hey, I put up a new crag and put the ascents in the system, after a few weeks, I have to make 1 or 2 adaptations (grade changes, name spelling) but it seems impossible to change a new added route. Can you help?
