Removed "Ad Column" for Improved Speed

My title says it all. I decided to do without my "ads" column.

Just sticking with the nitty-gritty.

Upgraded Validation

Just added focus to the field that contained falsely validated data. That is, when a validation error occurred, as when no input was entered by the user yet he hit "Go", the error message would then be followed with the cursor sitting in the field where the input must be entered.
