Google cant indexing private forum sections

Hi There,

I want to index my all forum pages from Google. Some forum sections are private and only for members. So Google cannot indexing these pages. Do you have any idea about that or issue?

Thanks a lot

Before all else thank you for reply Bruce. Actually you are right, it is sense.

So now lets forget about private forums, lets talk about private message/link on forums. I dont want to indexing google and guest users some part message on forums.

Can we use the code and hide some message/link for public users and google search engine? Like start with this tag [*HIDE] Private messages or links are here [*/HIDE] and close the tag. I think it is really smart idea and so useful, what do you think?

Actually I was trying to explain on this topic but I dont think people are understanding me?
