In that case, the Debt Elimination and Money Management subforum would be the perfect place for that journal. Sorry I misunderstood your question.

As far as this being a "public place", please know that only the Visitors Corner is visible to the public. All the other areas require registration and aren't available to the searchbots. You'll find many members posting budgets and other financial information there with wild abandon. There's no requirement you use your real name or need to post any other personally-identifying information, so you're somewhat anonymous.
