Im by phone now so i can't check that script, but lets try to agree on something.
You start editing that script how you want and when you stuck somwhere post and explain particular problem in Coding forum with your attempt to work things out.
Because this way with just posted link it is like ordering some script and for that should be used Freelance or Marketplace subforums.
Here post request with caracteristis of script, for exaple,
"does anyone have forum script with that and that",
"does anyone have download script which can do that and that",
"does anyone have that and that generator script"...And than the colective of this forum can suggest some type of script.
This type of requests simply are really not fair.
