Eventual Porting of My Site

Hello all! My site is The New Age of Trek. Basically, I am adding large quantities of pages to my web site, and will have several thousand by the time it is done. Right now I use Dreamweaver MX as it allows me to change my base template and synch with the site. Obviously, most of you are more advanced than this!

My question is, simply, how difficult will it be for me, say six months down the road, to port my site to some sort of news scripting or portal site, should I choose to do so? The reason I would do this is so staff, etc, could post articles, make template changes, etc.

It would probobly depend on what type of CMS you are looking to use. I imagine the 'free' ones would make this task none to easy. Do you have any plans for which ones you would like to use / have been looking at?

When you say CMS, what do you mean?

Also, I was looking at moveable type, what do you think of this?

A CMS is a content management system, something that would allow you to create a custom 'portal' or 'news site'
There are a number of popular ones out there - phpnuke, webapp, postnuke, etc.
