I think we should leave them as they are - except for the Custom Titles. I think Custom Titles are a great idea, and would add some more variety to this place. However, I don't think there should be a limit to how many posts you need to get one - surely they should be given out depending on the quality of the members' posts instead of the number? Anyone can get to say ... 4000 posts or whatever. Not everyone posts say ... 2000 posts that are quality
and contribute to this place.
Just my 2 cents
