Forum:Flip summoning

Hi I have some doubts about this and in flip summoning page is not clear: Thx and sorry because of being so noob.
 * 1) Can I flip summon a monster in the same turn I set it? (I think the answer is no)
 * 2) If a faced down flip effect monster is attacked, is activated it's effect? (In the page, at top it says "A Flip Summon occurs when you flip a face-down Defense Position monster into face-up Attack Position. Flip Effects will also activate if the monster is flipped face-up in the Damage Step or by being flipped face-up by an effect that does not negate Flip Effects" but at the end of the text says this "A monster flipped face-up by a card effect, or as a result of battle is not considered a Flip Summon. Only flipping a Set monster manually is considered a Flip Summon")
 * 3) To activate a flip effect the monster must be flip summoned in face-up attack position or it can be summoned in face-up defense position? (Maybe it has no sense if it can be changed from attack to defense position but I'm not sure).
