Dating a co-worker: forbidden?

Common wisdom is that dating a co-worker is bad ... very bad. That said, I do know of co-worker relationships that turned into happy marriages. There are a number of tips on this site to help make it work, but know going in that this is going to be difficult, and be sure you are prepared to face the challenges. Also remember that the co-worker may *seem* perfect because you are interacting in an environment that is ripe for emotional relationships. Be sure to factor that into your decision - that is really the person, and not just the circumstances, that appeal to you.
