Elvish- How many people can speak or are learning to speak elvish?

[Morgoth the Great]

i have always prided myself on NOT speaking elvish. i know the odd phrase, e.g. Mae Govannen, but i do not, and have never wished to learn either Quenyan or Sindarin. the reason for this is simple. it is not a complete language, and thus not everything in it can be. i also believe that Tolkien left it unfinished for a purpose.
