It has driven me more and more each day away from the WYSIWYG screen and over to the HTML. When I started I used the source screen about 3% of the time, now, about three weeks later I'm at about 50%.
If you are just starting out...you should try it.
If there is anyone out there who is already using it, I love to hear from you...can use all the tips I can get.
One more thing, if you started out building on free web space using an online editor, (like Page Builder at Geocities) you can download the whole site to WebPage without messing it up. Jobs that used to take me hours, now take minutes.
This is not a promo post! I just feel so many people (especially newbies) could benefit from the program.
