Hey guys, I just got Dawnguard yesterday and I'm really enjoying it.

I've just entered the Soul Cairn... now, earlier on I rejected the offer from Lord Harkon to become a vampire lord. I also rejected Serana's offer to turn me into a vampire so that I can complete the dlc as a member of the Dawnguard.

I'm currently a werewolf and I understand that if I change into a vampire, I can only become a werewolf once more?

I wanted to ask the following:

1.) After completion of the Dawnguard storyline, when Serana becomes a proper optional follower (I won't cure her), how many times can I be cured and transformed into a vampire again?

2.) What effects does the vampirism have on me with my membership of the Dawnguard once the dlc is completed? Will they hunt me down?

3.) What effects does vampirism have on me in terms of society? Will people be hostile towards me or act any differently than normal? Will my disposition to NPC's be slightly lower?

4.) Will I get a bounty for transforming into a vampire lord in public?
