The original CSY Topica list has a wealth of information from over 10 years of owners posting questions and answers. Though the 'Search' button on Topica hasn't worked for several years, it IS possible to search the list for a specific topic (and/or person's post) using Google search.
Go to Google.com and put this in the search field:
CPT autopilot site:http://lists.topica.com/lists/csy/
Note, this is an example to search for 'CPT autopilot'. If you want to search for seacocks, for instance, replace 'CPT autopilot' with 'seacock'. Leave the word 'site' in place, don't use quotes and use the rest exactly as written above.
This will bring up a typical Google search window with all the posts.
