Guys...I have good news for you!
I just discovered this a few days ago from one of the forums on CL. Apparently just HOURS after CL shut down the personals, a new site was born to replace it...and it's registered overseas (France to be exact!)
The site is doublelist.com and it's already booming! Keep in mind, it's only a couple weeks old but it does look to be the new CL when it comes to the personals. Read the FAQ or HELP section, they stress the site is only going to get bigger and better in the days/weeks and months to come. Please help spread the word and post responsibly, please don't post illegal stuff.
