Hi sir,
Check out
www.mashaworld.com/index1.html and
www.mashaworld.com
Besides movies and pics she has her own messageboard, and she does at 5 live shows a week herself, and her friends are doing like 5-10 a week as well. All in masha's house.
And yes you are right, retentions are great. Better then "normal" sites, because the ppl who join feel really connected with the girls.
Have fun in Vegas, and looking forward to get some of your traffic:-)
