Ok so, here are some suggestions for in game.
1) Make the log in session more than 5 minutes. ( I will be away and it'll log me out less than 5 minutes. )
2) Have a pk shop. Put special items in a shop and when you pk you get point a pk. The price of the item
will be the pk point. Example: Zammy god sword would be 10 pk points.
3) Add more easy training stuff. Like at home, there are those level 2 people in the jail, but you should get more
and scatter them.
4) Do a voter shop. Put never-before-seen items in that shop. And same as the pk shop, but with voter points.
Every two votes is 1 voter point.
5) Add more items in the shops.
EDIT:
6) ::bank command. You can bank any where instead of coming home every time.
