I have not heard of Word Press, do you have to know anything? Is it a fill in the blanks and go?
Well, you need to know some things to get it started, and you'll need to read the CODEX extensively if you are not already computer savy. But the process of creating pages requires little to no knowledge of coding. There are support forums and FAQ, which really helps. I've been filling the blanks as I go, going to forums for help and asking people I know if I get stuck. I don't know how it compared to SBI though since I've never used it.
