Bethy, get as well acquainted with the software as you can before you get started. It's not very user friendly as far as I'm concerned! Mine is such a mess right now!!
Be aware that you have the choice of making a post OR making a PAGE! Right now I'm thinking I should have had my different categories on different pages... but without deleting everything, I can't reorganize!
Only thing wrong with that, it seems that anything you, personally as admin, add to that page, can only be done as a "comment."
I also can't easily find where I can just "view" a comment or where to edit it. Seems it takes forever clicking here and there to find what I want or need.

Maybe it's just my thickheadedness, but I'm not sure of that, even!
You're not the only one frustrated.
