Sql-Ledger mailing list archives from Dec 2004 to July 2009 are available at http://archives.ledger123.com/. In addition to small index files (by thread and date), I have also created a one big index file which links to all postings. This will help you to quickly search the mailing list using your browser find button.
Special thanks to mailing list user ‘ziggy’ for providing the mbox source which I converted to html using mhonarc.
Sourceforge archives are also available here but seem to be censored by the Moderator. I was unable to find any posting by me.
