Craigslist Poster

I am a Real Estate Professional. ? I use Craigslist daily to post my properties and services but as you know its hard to keep those posts visible unless they get reposted, especially in the RE section. ? I have developed a system that allows me to post 10-15 ads 3 times a day, which also requires deleting the previous ads posted so the new ones don't get flagged. ? My system is working great other than the fact that it is extremely tedious and takes too much time. ? I have researched all the auto posting programs and? unfortunately? they all seem to not meet my needs. So what I'm looking for is some software that would preferably work in OS X, but I also have an XP machine if OS X is not possible, that will allow me to automatically log in to my multiple craigslist accounts, post my 10-15 ads 3 times a day and delete the ads that were posted hours earlier. ? I post ads in the following sections: Real Estate For Sale, Real Estate Services Offered, Housing Swap,? Financial? Services Offered. ? In the Real Estate For Sale and Housing Swap sections I add photos. It would be even more? beneficial? if the software could integrate with [login to view URL] service so that the recaptcha is automated as well.
