I think it means don't ask lots of unrelated questions in one thread. However all us newcomers are encouraged to look through the existing threads or do a search coz more than likely our question may have been asked before and is already answered somewhere.
Most of the others in these forums are extremely helpful, but there is only so many times you will get an answer to 'how do I print "Hello World"?' without being flamed
.
If your four questions were on different subjects then I wouldn't worry about it too much, at worst you simply won't get a reply.
It's never as easy as it looks!
