I don't know about anyone else, but I'm really beginning to dislike Yuku.
Not only are we getting bombarded by the pop-up ads (addressed in a separate thread), come to find out the Topics per Page is now set to 20.
If you want to adjust that value, you have to become a paid "supporter" of Yuku.
Here's the response I received for my inquiry to Yuku:
As announced last week at the Support board - http://support.yuku.com/topic/9558 - the option to choose the number of replies per page is now reserved for Supporters only. If you're interested in purchasing Supporter for your account, the information and links in that topic should tell you what you need to know.
If we can help you with anything else, please let us know.
