I think Piczzilla is on the money.
Any member can open a thread in the Ask Me Anything forum. That way, if you want to share, you can, you just have to wait for someone to ask you.
And for what it's worth, I tend to agree with Rick. Forums only work when the members have input. If you just want to read about photography, buy a magazine. It's the interactivity that makes forums great.
And to that end, I've opened up a thread in f/stop where you can ask me, Brendo, anything you want about my interest in Photography. Just don't expect to be dazzled with brilliance, everything I know can be placed on the back of a postage stamp.
