Welcome to the forum. We'll answer your questions, but a bit more information would help a LOT!

Is there a tag, and if so what did it say (everything, exactly)?

Do you have you photos uploaded somewhere? Flickr or Picassa? In order to post them here, that is the first step.

Your garden center has a book on a rack of garden books by Ortho, called All about Orchids. That's a great book and will help identify your plant if there is no tag.

Thanks for the reply.
here is the link to my orchids a year ago :

Phalaenopsis. Two of them. One has a kei-kei (plantlet) growing off the old flower spike. Bay window or no, east exposure or no, this plant has been chronically underlit. Everything about it screams "I need more light". Otherwise things look good. You don't need a LOT more light but you do need more. The blinds in the windows don't help. All there should be is the sheerest of curtains to take the edge off the hottest late morning sun. Anything more than that and you have to make the difference back up with artificial light. Do you fertilize? If not, then something off the rack at the garden center couldn't hurt. Repotting? Definitely I would cut the kei-kei free and pot it on its own. The two plants can be separated into their own pots 6" or so. Fresh phal mix and more light. Blooms next Spring... maybe this Fall if you really pour it to them.
