Searching talk list archives

The wiki page [[Mailing lists]] suggests two ways of searching the mailing lists but both seem to be broken links: am I right?

If not, what should I be doing to search Talk-GB for references to Sustrans and the NCN?

Thanks as ever.

As so often, asking too hastily and have answered my own question: there’s a link to ‘Nabble’ in the table against the Talk-GB entry.

I think the question stands in a sense: are the search suggestions linked to above no longer operative?
