Comments

Josh Berkus: I was an early (uncredited) contributor to SQL-Ledger, and part of the fork. The reasons we created the fork: - Many known security holes (reference early LedgerSMB releases, which fix these. They are still not fixed in current SQLLedger) - Primary developer hostile to outside contributions, and did not credit the contributions he did receive. Also relicensed contributions without permission. I know, because some of the contributions were mine. - Basically the primitive ancestor of LedgerSMB
