lets start step by step.
1- i don't understand validation
2-A list of HTML tags how to make them print their value in the txt box is the problem

3- Some javascripts and dhtml examples that user can add easy but the problem is as before

4-Some HTML templates because many people doesn't know how to make HTML pages! the program isn't a wysiwyg (what you see is what you get)

5- As you said , a FTP feature, so someone who made his web site, then to publish it! finally it is working

6- thanks for the link i didn't know it before
