Yeah, the RIU interface sux. It's a piece of ready made software for discussion forums, so you get what you get.
As a grower I am somewhere between advanced beginner and retarded intermediate. I feel most comfortable answering Newbie questions. Also, I find the newbie threads more useful because they make mistakes that I can understand and learn from. With the advanced growers, I don't know what problems they avoided since they don't come up.
Most of all it's very satisfying to feel useful.
