Nice site. A little bit of feedback:

- Once you click on "Settle Debts", it's not clear how to get back to the list of expenses.

- I like that you auto-create debts and participants from entries. The downside is that if I make a typo in someone's name, there doesn't seem to be a way to delete that person, even if I delete the transaction w/the typo.

- I mindlessly entered $10000 into the expense field, and it was automatically changed to $9999.99. What's the reason for the $10k cap?
