Announcement or Block based on post count?

[Adam Metzler]

Is there a way to have a block show or some type of announcement that will show to members based on post count. I am looking to have some text displayed in a block to members with 0 or 1 post. Just wondering if I missed something. I know I can do a custom block and assign certain member groups to see it only so I know I can do it that way but it is a bit of setup to do it and was hoping there was something I could do just based on post count to keep it simple. Thanks!
