"Just curious on how much money you bet and how often?"

The amount I bet depends on how well I expect that sport/bet to do. Most of my bets are between 2-5% of my bankroll.

How often? Well I turnover my bankroll around 3 times per week. I am pretty aggressive though and make alot of bets.

"and how do you decide on what to be on"

Whatever I have an edge on. Some of this comes from my own handicapping, a good chunk comes from smartgambler and the rest comes from other people I know.

I bet on AFL, NRL, Super 12s, tennis, MLB, NFL, college football, college basketball, NBA, NHL and golf. I'll make 4000-5000 bets over the next 12 months.

All the picks from the first 3 I get from my own handicapping. Tennis, MLB and soon NBA I get from smartgambler. Most of the rest I get from people I know.
