In particular, see hack (his response) mode, day mode, night mode, demo mode, fireworks mode, and yoyo mode; also talk mode. One also often hears the verbs `enable' and `disable' used in connection with jargon modes. Thus, for example, a sillier way of saying "I'm going to crash" is "I'm going to enable crash mode now". One might also hear a request to "disable flame mode, please". In a usage much closer to techspeak, a mode is a special state that certain user interfaces must pass into in order to perform certain functions. For example, in order to insert characters into a document in the Unix editor vi, one must type the "i" key, which invokes the "Insert" command. The effect of this command is to put vi into "insert mode", in which typing the "i" key has a quite different effect (to wit, it inserts an "i" into the document). One must then hit another special key, "ESC", in order to leave "insert mode". Nowadays, modeful interfaces are generally considered losing but survive in quite a few widely used tools built in less enlightened times.
Personally I upload to YouTube and I would recommend sticking to that, but something like Streamable works aswell. After you have it uploaded to YouTube and you want to keep it organized (in case there are too many videos) you can either name them Playername+1/2/3 or have playlists in which you add videos for every player for easier sorting.
