Member Testimonials

Open Member Quote   Just had to post a note to say how impressed I am with this site. I only discovered it a few days ago and I have to confess that I am a TOTAL non-starter with computers...but very keen and willing to learn! :D I have asked for - and received - prompt help in partitioning my hard drive although I decided after sucessfully doing it, to go back to normal coz other stuff confused me! Still, I am upgrading to a faster processor and bigger hard drive in the very near future so will be carrying out the procedure again (I hope) Just wanted to say how grateful I am for the support and I will be recommending the site to all my friends - peachyglint1  Close Member Quote
