I've found that mfrs especially have an irritating habit of redesigning their websites every year or two, rendering all my bookmarks for 'em useless till I update all the URLs. And forums can move threads into "archives," killing the saved URL for them too. So instead of saving an entire thread that may only have a few posts I need to keep, I've always just copy/pasted the posts I want to keep into a Word or Notepad document that I then save to the appropriate folder. As of this writing my "marine" folder in my documents has 918 files in 98 folders, organized by categories and then sub-catagories so I know where to look when I need the info in one of 'em. And as long as I keep 'em all backed up to a flash drive I can never lose 'em.
