Re: How to in wiki-6.1?
I have found that some themes can obscure or not even call some page features. You have to try different ones. Know what's important to you, install a theme and check all the sections to be sure they show up like you want 'em to.
You can also change the way some things look in CSS. Sometimes you do have to edit the .php file for the page and save those changes somewhere so you can change 'em again when you upgrade.
I have never gotten any of the whose online type modules to be work right.
That said, I have found Tiki to be incredibly powerful and worth the learning curve and the occasional annoyances.
