I agree with Anxiety. It makes your forum look empty/inactive.
Still, they're nearly all being used.
Our forums are always being used, our forums use all different bits.
Just makes them more active, I guess...
More sections doesn't make it more active. Also, at the moment they're being used. Once you have a slow period which you will, it will make your forum appear inactive.
Also, those tabs are the horrible tabs. Labrocca's tabs are the best ones, they're instant. These ones have delay. I seriously think you don't have enough content to require tabs yet personally.
I'm buying subscriber right now, I'll implement them.
Ill cut my sections down over time, guaranteed.
