I’ll just contribute by saying that Stacks3 is a must buy… It opens the door for you to use hundreds of stacks that will do just about anything.
Some basics: All RapidWeaver is doing is creating HTML/PHP pages (html/php files). Those files get uploaded to your web server. The web server has NO CLUE what created those files. Likewise, Rapidweaver only UPLOADS files to your server and basically has very limited info about your server and what has been uploaded. For example, if you rename a page and upload it with the new name (file name) the old file will remain on your server. As soon as you rename the page RW basically “forgets” the original page. Thus, you must not only learn some things about RapidWeaver and how it works, you also need a basic understanding of your files on the server. For this you will need to use either you web hosts control panel (file editor) or do as most people and get and learn a good “ftp” (sftp) app which is used to see the files on your server and maintain them (delete old ones.) But you need to learn first as deleting files on your server is something you don’t just start doing without knowing what it is you are deleting. NEVER delete a file on your server if you don’t know what you are deleting. A “guess” is not good enough.
So learn, learn, learn.
Learn Rapidweaver, Learn Stacks (and Partials in stacks!), learn about 3rd party stacks, and learn about your server and using ftp apps. Sounds a bit daunting but just take it slow. Start out very simple, and learn in steps.
Most importantly, read these forums every day and you will learn much. I’m short on my coffee this morning so I hope all that makes sense.
OH… and I know you say you are not new to web design so if I covered anything you already know just ignore that… just trying to cover the basics not knowing your past experience.
