Potted Orchid

I recently became the proud owner of two orchids. I've never had to care for orchids before and they are so delicate looking. I searched for a good website that would highlight how to look after them without going into too much detail. I found the excellent Beautiful Orchids. 
Spraying water on the leaves is something I should avoid. 'When watering orchids take care to avoid wetting the leaves' - it states!  I thought a little water on the leaves would be a good thing as they are native to tropical rainforests - but No!
