Help Identify - Tall Growing with no Flower

[jmcnyc]

I received this orchid as a gift. I don't know what it is. The Orchid was slow growing and it grew one stem which is now droopy (you can see it towards the bottom). Should I cut it off? The second stem grew fast and is now about 18 inches tall. I think this is a result of moving it to a sunny window. Some of the leaves have brown tips as you can see in the picture below. I stopped fertilizing it and the brown tips seem under control. It seems healthy however it is not growing any blooms. The soil is loose bark and I water about once a week. Any help in identifying and telling me what I am doing right/wrong?
