Ok - that explains a few things
1 - I'm a big believer in the warning page. As long as the surfer can see the enter link without scrolling, you'll be safe (and like I said, you'll have an extra page of ads)
2 - I did not know this was a hub/personal site - which is fine, we all have them - sorry I assumed it was open the the public. I still think my idea of splitting them into seperate categories is a good one - hell, you could also link directly to those pages from a gallery or free site that you built (link to the brunette section from a brunette gallery) You could even go a step further & make a waring page for each category
As far as opening it to the public, that's all up to you. There are pros & cons, but if you're feeding it a decent amount of traffic right now, just keep it for yourslef & then re-evaluate it down the road
3 - 2-3k unique a day is nothing to sneeze at
I think you had a thread going where a couple of us spoke about how your galleries are st up. I still think that header is way too big for a gallery page. I think you could easily shrink it done to about 1/2 it's size, load it on the top left, have 2 thumbs next to it on the right, then 2 rows of 4, then 2 thumbs on the bottom left with some suggestive text on the bottom right.
I get the feeling that you're a TGP when I look at the 1st page, but after looking at the galleries, I get the feeling that you're jsut a large free site. You mgiht want to either change up the templates on the galleries (use 10 or 12 different versions) or add in some sponsor hosted galleries.
