They seem to have merged, however, not in all places. I still login at TUAU, and schedule jobs through them, and do reports on their site, but am always sent their newer FF jobs through Kern.
I went to TUAU's website this morning after I saw new postings on MF's website of the ones I did for TUAU. I clicked on my state at TUAU and there was 'nothing' for us. I gather all of them have gone over to MF.
