With Montezuma, you don't have the number of options to build your CSS style sheet for you, you have to edit the CSS files yourself. There's pluses and minuses. For someone new, the Atahualpa style options is easier, but once you have a handle on CSS and something like FireBug, it's easy to add the CSS in directly. Several times I've given a solution to add something to the CSS inserts and then realized that there is an option that could be used instead.
Anything new is more uncomfortable than something you alteady know, but that's what learning and exploration is all about. Dig out your inner kid and explore and make a bunch of mistakes, it's the best way to learn. Just realize you won't learn it all in one day. My latest 'project' is using a Raspberry Pi (with a couple thermo probes attached) to send the temperatures they record, every 15 minutes, to a program at our website that stores the data in a database, checks if the temperature is too low and if it is, send out an email alert to a number of people. In addition I have a program on the server that checks once an hour to see if it got any data (could be a power outage).
I started this because we had a couple pipes freeze. When I started, I just had an idea and persistence (and Google). I didn't know how to connect the sensors up to th ePi. I had to find and modify a python script to read the data and add to that code to format and send an http request to the server. I had to figure out how to make it run headless (no monitor or keyboard) and I've got version 1 working. I ran into a problem that it would work for two days and then stop, so I had to figure out what was causeing that (a bug in my code). But now it works.
For version 2 I'm going to turn the code into a plugin for our wordpress site.
