Firstly I want to start by saying what an amazing system Eric has put together here - It is truely a good piece of software.
I am currently running your newest beta (1.3.9) on a Linksys WRT54GL and I am experiencing some issues witht the quota system.
Here are some of the issues I'm encountering:
1. Whenever I change a users quota, the system stops showing quotas for all users (Status --> Quota Usage), and I have to reboot. I'm not sure if the accounting of quota are still running. The chain (Chain egress_restrictions) are missing after a quota change.
2. Whenever I reboot, or the power goes down as it does often in South Africa, I seem to loose all the quotas that was assigned, including their usage so far.
3. If a edit a users quota, the usage goes back down to 0% - which is a bit annoying, but one could work around it. I believe this is an issue with the IPTables being cycled. Al the quotas also seem to go missing.
Is there anything I can check to try and sort this issue out?

Thankz
