Reply to Recommended DJ Sites?

Can anyone recommend any good DJ sites that offer good tutorials and tips? I've watched youtube vids on Ellaskins and a few others plus I've checked out this community for tips and also DJ community 's website. Im looking to improve my mixing and I'm stuck on phrase matching songs. I can count my Beats and Bars and I know something changes every 4 / 8 bars in songs but there's something I'm missing because my mixes seem forced most the time and I can't get my head round it. I mix all genres but mostly Top 40, Hiphop and R&B.
