A question

I am trying to make a mirror is there anyway to make the surface look somewhat reflective?

Nope.

The best you can do is make a material "shiny" which only reflects the sunlight slightly and does not reflect anything near it as a mirror would.

There are some camera tricks that simulate a mirror only for the one player - that is, point my camera at me. I think I saw some of these gadgets for sale at "Bravo Bravo".

You can make it look shiny, but not actually reflective. Mirrors are beyond SL's technical capability right now.

If all you want is a shine though, first make sure you have shine turned on in your preferences. If it's not already on, you'll need to restart SL after you turn it on. When you come back, get ready to see the world look about 10 times better than it did before. Shine is the one graphics option that makes the single biggest difference out of all of them.

To make an object shine, select the object and then go to the texture tab on the editor. There's a dropdown box with 4 settings for shine: none, low, medium, & high. The different settings change the way sunlight reflects off each surface. High shine will produce a dark silvery appearance, kind of like the surface of shiny sunglasses. Medium & low will display the affect to a lesser degree. Low shine is best for preserving the original coloring of the texture while still shining.

Again though, none of these options allow for reflections of anything besides sunlight. Making an object shiny will not cause it to reflect other objects in any way.

you also have the option of making the surface ( lets say a floor) 35% tranparent, then simply add upsidedown duplicates of the objects you want to reflect and place them below the originals.

Devils Moon Sim also employs this illusion

heres a pic of one of my old stores to give you an idea
