I don't get dawnguard until they decide to release it to us lowly PS3 players but I just have a few questions regarding the new items available for crafting
1. Can we improve silver weapons?
2. Are there any items that were previously not able to be improved through smithing that can now be improved? (mainly the Headsman's Axe and the Dragon Priest Daggers)
3. Are there any new craft-able items besides crossbows, bolts, dawnguard weapons and armor, and dragon bone weapons?
4. How do the new weapons and shields look when put on display racks/cases/and plaques?
5. Are there any new items that could be placed around the players house as decoration?

1. No
2. No
3. Arrows, Shellbug Helmet, Bonehawk Amulet
4. Most look just fine, though I'm unable to place the Dawnguard Axes in any rack.
5. Many, though I won't list them in the General section of the boards.

THANK YOU!!!
I've been looking at the [censored] wiki all day and could not find any articles confirming or denying the rumors of silver weapons and [censored] being tempered!

Glad to help.
Just as personal preference over many, many years in the TES world...avoid the wiki and stick with UESP: http://www.uesp.net/wiki/Skyrim:Skyrim

i checked both but there is no section that confirms or denies rumors and it really grinds my gears lol

Ahh, understood. Well, glad to share what I've experienced.
Have a nice evening.
