Hey I am a fan of your posts and I just want to point you to my blog and a couple of powershell scripts

I have created them from a hodge podge of sites ( yours for one) and just trial and error, not a programer just old school administrator

I was hoping you could improve them or post them for others to use, my blog is not all that popular but I want to share.
