Hi, every senior member:
I let some blocks present in the right block, but it must login member account to see the block, but I want to let guest to see the block. I set the block order, but it doesn't work. Could somebody give me some advices? Thanks.

I am not sure if I am understanding the problem correctly so first I will summarise what I think you asked:

"I have a block that is only visible to registered users but I want to make it visible to anonymous users too."

Well, if you want to make a block accessible for anonymous users you first go to the admin panel. In the admin panel choose System->Groups->Anonymous users. In that screen look for the block name and tick the box next to it and confirm. That should generally do the trick.

If this is not what you meant to ask please clarify.
