I have been on totallyphotos for nearly 2 months. My portfolio is now almost 50 photos and I've made 7 sales so far. It's getting busier on the site and my last 3 sales were in the last week. (in the beginning it was quite slow)
It's a startup site but seems to be growing. It still has a way to go to reach the traffic of the more established sites, but it seems like a good start.
Hope that helps.

Thanks for the tips ... now I just have to wait for the next storm!

We've had a few storms around here recently - with some great lightning displays. Are there any tricks to capture shots of the lightning bolts during the day?
If I leave the aperture open I get an overexposed photo, if I try to 'catch' the lightning I seem to miss it every time.

Any tips?
