Create a Quest Log?

So I'm creating my first RPG and I want to create LOTS and LOTS of quests for my players to enjoy. One feature I particularly enjoy in an RPG is the ability to view a journal or log that holds info on current/completed quests. The question is, can I add this to my RPG, or is it even possible? I'm pretty sure that I would need a script or to edit some code or something, but I don't know anything about any of that.

Another quick question while I'm here, is there a way to pop up a full screen window that contains text information in it? For example, if I was to put a poster on the outside wall of a building in my game and I wanted that poster to contain a lot of info, is there a way to get that info to pop up in a large, full screen form? Maybe even navigate back and forth between several full screen pages with the directional buttons? I'm just curious because I am using the "Show Text" Event and it pops up in that tiny window and I cant really put all the information I want in that window. If that makes sense.

Yes, it is possible and it has been done. You can use both evens or scripts to make what you want. There are lots of scripts for journals/quest logs, and I remember seeing one or two for 'book reading' (which allows you to do something similar to what you ask).

Try a quick search on this forum and if you don't find anything, try Google.

For the Quest Log, there are several script... although it can be achieved with Common Events and items.

For the poster/book, you could always use "Display Picture" or Scrolling Text.
