Walks entered on your group's website are published to the Ramblers website through Ramblers Walks Manager. A question that comes up regularly is why the Ramblers listing shows no leader name, email address or phone number, even though they were entered on the walk.
The answer is that, since Ramblers Walks Manager went live in June 2023, Ramblers only show a walk leader's details if that leader has given permission in their own Walks Manager contact preferences. Nothing entered on the group's side can switch that on for them. It takes a couple of minutes and each leader only has to do it once.

This applies to the listing on the Ramblers website only. On your group's own website, the walk leader contact link is handled by the site itself, as described in Walk Leader Contact, and does not depend on these preferences.
A short email to all walk leaders with the three steps above, sent when the group first starts publishing walks from its site, saves a lot of "why doesn't my name appear" questions later. This page can be linked from that email.
