This modification adds a magnifying window to your forum. See the screenshots for more info.
I will not be offering too much support on this as I have deleted it from my forum after I wrote the instructions and took the screen shots. I have no use for it, but was requested by a member.
Sorry, I didn't spend much time putting this together. Maybe someone could make this a little better by adding an option in usercp for a member to choose whether he/she wants to use the vB3 Magnifier or not.
