[SL internet usage?]

Hello, everyone. I was curious how much interent usage SL eats up. I have an allowance each month of 250GB (which I think is a lot), before I get capped. I share this with 3 other people and gaming on xbox live. I just want to figure up how i can use sl along with everyone wanting to game and youtube. 

[I have tried for two days to buy]

Seems to be a common thing this week. I am also having trouble have tried every solution given to me and yet NOTHING seems to be working. Its a bit annoying. :C 

[Are there problems with buying L$ lately?]

I have tried for about 3 days now to purchase it. Its starting to become a pain LOL. I need to finish stuff up with my shop and pay tier but now im afraid it wont get paid on time. Have there been any issues lately? I know im not over my limit. And when I try to purchase them from phoenix viewer the thing loads but there is no error.. and no lindens added. I did however notice that when someone purchases something from my store i need to relog to see the new balance, but the lindens i bought do not show up. 

[Is the Pheonix viewer really leaving us? :c]

Makes me super sad if it is. I tried firestorm last night.. not a fan.

[What is debug view in the advanced menu?]

I use Phoenix and was curious. Im still having camera view issues.

[How do i put my camera settings back to default?]

I was building and somehow my camera is a bit off. Even when i press esc. Its a tad annoying. Almost as if my avi is too short for the camera look. (not mouselook, it works just fine). I adjusted the camera controls but it just goes back to this view. HELP ME D:
