Fix a bug: contact_form.rb - Instead of using all <input> & <textarea> tags from the page, use only for the given form.
Fix a bug: email_pool.rb - Random function generated numbers only between 1 & 5. Instead they should be between 0 & 4 to match the indexing of an array. Fixed.
Form Validation: Added some rules around method & action attributes of the <form> tag
