Just a quick note regarding web browsers (aimed mostly at new Mac users). When I used to/had to use Windows I used Internet Explorer (IE) and then progressed to Firefox. On Apple Macs IE is not available (hurrah!) so what are your choices?
My 3 main browsers of choice are:
Firefox – Available at getfirefox.com
Camino – Available at caminobrowser.org
Safari – Available at www.apple.com/safari
Depending on the website you visit you may find one of the above browsers more suited than others (for example, Camino for Wordprss blog editing).
