1. I'm sure, it was a bit confusing but it says "$0.00 of $0.00 used" so there's a zero limit.
2. I don't know if it's been 30 days since I bought L$, but my 0 limit of selling changed, so I sold them for US$, it has not been 30 days since selling the $L, so do I need to wait that long before I can process credit after selling my L$?
3. I'm aware of the limit page, have it pulled up. Though I feel like there's a lot of information that's simply not available and you need to be told this by someone else rather than reading it somewhere, which is annoying. I like being able to look online and see step by step instructions. SL doesn't seem to have many of those.
