I recently found a nice website describing how to solve level 17.

Again, If you don't want the puzzle spoiled for you, don't click on this link.

So if you need help with level 17, and don't mind getting the level spoiled, go here:

in the solution for Buzzle-3. the hint stated the small latter is surrounded by EXACTLY 3 big letters which leads to [A-Z][A-Z][A-Z]([a-z])[A-Z][A-Z][A-Z]. how did u figure out the small letters on each side
[a-z][A-Z][A-Z][A-Z]([a-z])[A-Z][A-Z][A-Z][a-z]
and from where did u get that u must join the letters.

i think that the questions are some kind missleading ....
