Hi Tina,
I took a quick look at the site, jumped into the members area (thanks for the temp free pass) and looked around. I don't see any glaring problems at all with it. Well except content being a bit thin, but thats to be exspected with a brand new site. and as far as I am concerned, 30 sign ups with less than 500 uniques isn't bad at all, esp depending on where your getting your traffic from. Keep in mind that spam is a major concern for a large number of surfers, so you may want to throw up a privacy statement saying you will not sell, trade or give out any e mail addresses at all, but the idea of giving up an e mail address will still cause a few surfers to shy away. spam is evil and everyones afraid of it heh heh. Content wise, more pics (I see you have guys coming *no pun intended* soon) and content is also posts on your BBS and personal adds section. A friend of mine used to get submitted pictures from surfers, make TGP galleries, submit them and get even more surfers to come to his free site and send in pix. Took him around 2 years but he was making between $5,000-$7,000 a month from his freesite and sponsor links. He turned it into a members area and I understand is doing quite well. May be something you could consider trying if you can handle the bills at first of getting listed like on something like the hun.
As it stands right now I think your site has a lot of potential, just be patient, nurse it along and keep working on it, Never hurts to ask those wiser than I for more advice on it.
Good luck with this site girl, who knows, I may sneak in there and get my own membership to it
