I'm sure i've seen that hack somewhere...

Well, what i want is somethink like this:
The download link only would be available after the user post a "Thak You" post...
I already have the "Thank You" hack, but how can i 'hide' the links until a thank you is posted???

Thanks in advanced

I think you may be thinking of the hide hack. This allows you to hide sections of a post unless somone has replied, or is from user group X.

Look for addons for the post thanks hack, I believe that addon has already been released here or at vb.org. Not sure though.

Can't See Attachments Before Thanking a Post
This hack is an add on for Post Thank You Hack. This hack will block users from viewing or downloading attachments before they thank the post where they want to view or download the attachments.
