Migrating from AdRotator plugin

AdRotator
plugin is a simple file-based ad rotation solution. It was developed by
Angsuman Chakraborty long time ago, but occasionally we have the same
plugin names from WordPress’ point of view. If you are using this plugin,
you may click upgrade link from your Plugins page and it being replaced
with Ad Rotator widget.

So now you have two ways to solve the problem 'getad()' function is undefined:
1. you can download AdRotator and ignore upgrade notices, or
2. you can upgrade your theme to use Ad Rotator Widget.

Here is how to upgrade your theme. Find all occurrences of getad function,
and replace them with something like this:

register_sidebar(array(
  'name' => 'ad-area',
  'id' => 'ad-area',
  'before_widget' => '',
  'after_widget' => '',
  'before_title' => '',
  'after_title' => ''
));

Make sure you’ve replaced ad-area with the name suitable for you. Also
you can specify additional options, like before_title and after_title.

Then open the Appearence/Widgets page in Site Admin and configure
Ad Rotator widget instances for your advertisements area. Just take into
account, that in files for AdRotator ads are separated with new line
character (ie each line means separate ad), but in Ad Rotator widget
you should separate you blocks with <!--more--> (so each of them
may contain more then one line.)

Anyways, sorry for сonfusion, I did not want to сheat on you.
