Help for those trying to paint over wallpaper

I wish someone had shared this with me when I was fixing up my 1st house, so here is some helpful info if you don't want to remove the wallpaper:

1. use an OIL based primer and paint to change its look.

2. REmove the wallpaper ONLY if you know that it was put on correctly and will not harm the drywall underneath, otherwise, get some oil based paints!

3. IF you choose to ignore this advice, let me share my experience with you, I painted with water based and it activated the glue or something and caused the wallpaper layers to bubble! I freaked out since removing this paper in my house had already caused damage to drywall in another room so then I cried for awhile and then just went with it. Needless to say, it looked terrible and probably made me have to take thousands off the asking price.
