We have updated the indexing of caves.org for the "Caving Seach Engine" swicki.
The total number of pages indexed from caves.org is now 3,417, so if you use the swicki to search you should find more pages from caves.org at the top of the search results.
You'll find the caving swicki search engine at the bottom of the main forum page. Unlike regular search engines, the swicki is tuned to give you only caving results on searches. You can also "teach" it where to look when others put in particular caving search terms. Give it a whirl.
If you'd like to use the search engine on your Web page, drop me a PM and I'll send you the code to include it.
