No, they only associate with the religion they are not official members.

Yes, but only if you follow the correct dialogue lines.
No, she is an essential character and so can't be given to the Blades.
Skyrim Dawnguard adds the characters Serana and Velerica both who are Daughters of Coldharbour, which means they are pure blood vampires who had there powers given to them by the Daedric prince Molag Bal. Molag Bal is also known as the Daedric Prince of Domination, vampirism, corruption, slavery, and RAPE. If you speak to Serana about becoming a pure blood vampire she'll tell you it involved a degrading ritual were the women offered themselves to Molag Bal, which means Molag Bal raped Serana and Velerica.
Last time i saw her i was fighting giants outside of Whiterun and she got threw into the air and i haven't seen her since. Help?!
You can marry any NPC character in Skyrim through the use of console commands. With the exception of Serana from the Dawnguard DLC (There might be a way to marry her, but I haven't found it). Vivienne is not a character who can be married without console commands.
Were you infected with Sanguinare Vampiris? You may have became a vampire without realizing. If this is a glitch then you could try asking Serana to make you into a vampire, then talk to the dawnguards. They will give you a quest to cure your Vampirism and you should be fine after that. If you can't become a Vampire from Serana skip to the second step and talk to the Dawnguard.
only thing i can can think of is fire resistance but here's a tip if you have got dawnguard and have got auriels bow ask serana to put her blood on elven arrows and use the arrows with the bow (the arrows would be called blood cursed arrows) shoot it at the sun you will get an achievement and it will block out the sun so you just say bye to those weaknesses
To transfer wardrobes, first empty out all contents and pack them securely in boxes, making sure to protect delicate items. Disassemble any large furniture pieces and wrap them in moving blankets. Label all boxes and pieces for easy reassembly at the new location. Finally, transport everything safely to the new location and reassemble the wardrobe.
First of all you need to become a Vampire. Since you're asking this question, I'm going to assume you already did this. So, what you need to do is quite simple to join a clan. You need to go to a place where there are Vampires (Caves, Ancestral Tombs, etc.). Then you need to talk to all the Vampires until you find one that can give you quests. You can usually pick these characters out of the bundles of Vampires that are in some places because they always look really important.The Categories of this question is so wrong.
