Okay, I've been browsing around and I realise that people who try their best to contribute don't get the rep they deserved. Instead they get a bunch of leechers saying "Thankz" without giving the rep.
While I'm sure they appriciate your simple "Thankz" post, they would GREATLY appriciate it if you take the time to hit that +rep button at the bottom of their post.
Okay.
FIRST STEP
Go to the helpful guide/post and click the little +Rep button
SECOND STEP
Type whatever you want into the "comment" field and click "Add to Reputation"
Voila! You just made the person who helped you with their post HAPPY.
You should do this more often instead of saying "Thankz (filler)"
