Veteran wordpress user coming back. Any tips on getting info?!

Hey there! After running one of the top Windows 7 and Windows 8 blogs and taking a year hiatus, I’m back to working with sites again!

I was wondering if you guys could give me a few good sites for information for me to kickstart again. Here are some I already visit:

– copyblogger
– johnchow
– problogger
– WPMU
– SEOMoz

Thanks for your tips!
