"2D" effects

Hi!

I was just wondering, how would you archieve these kinds of effects:

  1. text blurring (or anything other blurred).
  2. Fade in/out effect with or without lighting enabled.

  1. Draw it to a small texture, then draw the texture on a quad, and let the texture filtering blur it for you.
  2. Change the alpha value of the colour(1 for fully visible, 0 for completely invisible)

For blurred text could you draw the text (lets say 3 time) slightly off each other with lets say an alpha value of .5 ?
