I have a couple of quest i wanna make, but don't know how to do it. any help would be very much appreciated.
Try reading the various script and general tutorials in the tutorials sections and then post more specific questions when they arise, you're more likely to recieve help that way.
Making the quest is the easy part, getting a journal entry in is the hard part, theirs a tutorial for this in the tutorial area I think under scripting.
Personaly I prefer using dialog to add quests, I don't like to see tons of scripts in my override folder, but sometimes diALOG IS NOT AVAILABLE.
