Best way to use Trophies and User title ladder for a new forum?

[NandorHUN]

Hi Guys!
I want to creat a simple user title ladder (and Im not sure about Trophies). I want to make it simple to encourage users to use the forum. Also use the forum if possible instead of chat.
Can you recommend me a good way to do it? Or can you recommend me a site that makes it good and simple?
I also dont want to annoy my users with it....

Thanks.
