[Help] Additional Configuration

[fluxbox]

Tried setting up this a few months back but was stuck on the reg part. Will continue working on this just a few questions in my mind:

1. Change rates ( EXP / GOLD ) etc.
2. Cash Shop Setup/Options, I'm thinking of putting the CS items available thru NPCs.
3. What are the current limitations, in terms of features, are there any that is present on official that is not supported or not working?
4. SQL BAKs when restored is just way bloated, I'm curios why it needs 11GB for the Character part.

TIA.
