Transaction fees: How do I collect them?

[cwm9]

I have so far managed to mine two blocks.  I'm confused because I thought that when I mined a block I was supposed to collect transaction fees too, but I only collected the 50BTC each.

Do I have to do something special to collect fees?  Do I have to do something to my firewall?  How many BTC should I expect in fees with each published block?

this guy. 3 posts, total noob, probably working for a mafia/fed reserv and collected 100btc and wants to collect more 'fees'

do you even care about making this a legit currency or just making $?

You get them automatically. In those blocks, there must not have been any fees.
