That's how it already works.
If they get accepted ingame, they are to look at the guild information and see the site, and are suppose to click it. And if people see new IGN's running around, they're suppose to ask them "Are you new?" and if they said yes, then they are suppose to ensure that they come to the site.
That's if they join the ingame first.
They do have the option of submitting application on the GC forum, or the KK site first if they chose to, which of course would make things very much easier. However, for the most part, people don't go to the forum, and if they don't keep up with the forum, they'll never know the true aspect and fun KK really is, and because they would be reluctant to go to the site, they would not be all that much of a committed member, and so removal of person is to take place.
Though the guild list is to undergo a sweep which will be done sometime from monday-friday.
