Care.com. You can sign up for free and they will let you post babysitting jobs for free, but you can't respond to any of them for free and any phone #'s the potential sitters send you are x'd out in the emails, ie xxx-xxx-xxxx. You have to upgrade in order to get any info, you can't even email the people back. Actually I didn't even realize my request went through because after I filled out the info for the job I got a "upgrade your membership" so I figured you had to have a paid membership for the job posting to go through, and at that I decided I had enough of that site.
You know, I'd be okay if they wanted to charge but I really detest when sites do that kind of thing, claim you can sign up for "free" but you get absolutely no good out of the site unless you want to upgrade. That ticks me off.
We don't go out often, DH and I. We've gone out together just the two of us twice since we've moved here. Once we left the older two with a neighbor when the first part of Deathly Hallows was released, The second time was this past summer when we got a sitter to watch the 3 boys so DH and I could go bowling and unfortunately that girl is busy.
