Not posting the same thing in two forums but posting one thread and make it appear in two forums so that people in both forums can see. Something like symbolic link in UNIX. Is that possible?
This is only possible if the thread is moved to another forum, leaving a link in the original forum. This can only be done by mods/admins. Replies to the moved thread will not bring the link in the original forum to the top though.
You should pick the forum where the question is best suited. If you have multiple questions that are not related, you can post the different questions in the appropriate sections.
