Its always hard to decide what to do when there's an update especially when you have made changes and there's at least one update each year. I do take notes of my changes but I am starting to think that I may not do the small updates but do a rebuild instead maybe every 3 to 4 years to keep the script up-to-date.... unless there's a major feature that I really want or need. The good thing for me is my site isn't a classified but more of an information site so I think I can get away with it.
