HELP PLEASE!? Paint/Posters? Okay, around a year ago my dad painted my room. I don¡¯t...

Okay, around a year ago my dad painted my room. I don¡¯t know what bloody paint he used all I know is it was markedly good quality paint. BUT NOW, I cant put any of my posters up because the glue-tack wont stick to the wall! Nor does cartridge. And there is no way contained by hell I¡¯m going to go out and buy 700 little pin thingy. Any idea what I can do to cause them stick?!
Answers:    You could try and re-paint the room. Maybe he used a paint that was for furniture only. You enjoy to go through a lot of steps though to re-paint but it will be worth it.
Go to your local hardware store and ask THEM. OR, you could other try a hammer and LITTLE nails...
