I'll be in charge of our school site, which needs some updating to be more professional looking. Most likely a complete redesign. I was thinking of developing with php/mysql...only because that what everyone seems to do. I have no issues with learning it because it interests me, BUT I want to make sure I'm choosing the right path to design the site. I want to be able to easily update text, add new pages, images, etc. Users will not be loggin into anything (not yet anyway).
If I did the php/mysql, am I creating my own CMS? I know what wordpress blogs are, but I see it mentioned in a lot of CMS discussions. Why would I use that or why would I design my own? Where do I start? What do you guys think my best approach or some of my options are? Do I even need CMS? Is there something that I don't know about?
