I posted them knowing they could be used freely by anyone
No I don't mind. I'm glad you liked it. next time, though, if you want help with something ask for it in the help section, and let people decide if they want to help. Most of the time someone will, Even on complex problems like this. Personally, I think I would've done it anyway, but posting a challenge, and "do this for me", are two different things. know what I mean?
