在console里多按几次return就注册上了(本来还想丢crontab的…)：

去邮箱激活账户。大功告成！

linux console里玩bt，绝配是rTorrent+screen. 熟练工就不废话了。这里只记录一下screen和rTorrent的快捷键备查。

添加和删除 torrents
回退键 用 URL 或者文件路径添加，采用 tab 键查看目录内容并自动完成，支持通配符，例如: ~/torrent/*
回车键 和回退键一样，但是添加的 torrent 保持非激活( inactive )状态 (用 ^s 激活)
^o 对选择的 torrent 设置新的下载目录，仅仅对还没有被激活过的 torrent
^s 开始下载，先运行 hash ，除非已经做过
^d 停止激活的下载，或者删除一个停止的下载
^r 初始化 torrent 的 hash 检查

注意： ^s 和 ^q 在 shell 里面经常用来控制屏幕的暂停，这会和 rTorrent 发生冲突，用 stty -a 来检查是否已经被使用，删除的办法是：

stty stop undef
stty start undef

before running rTorrent (or reattaching to screen) to leave them undefined. You could also replace undef with some other code — ^p, say. ^d also usually sends end-of-file but ncurses passes this through to rTorrent. stty eof undef if you are worried.

To fix this, you may also toggle the flow control in screen with ^a ^f until screen displays “-flow” in the bottom left corner.

Common Error Messages
