paid subscription registration warning
 

fellas-
here is the question: how do I customize either, the default notice that tells you you are missing privalges or need to register before posting.. and/or create a special notice that pops up like the one mentioned abovethat can alert the user that it is a paid forum?
If you go to one of the paid forums and are not logged in it tells you about 2 or 3 wordy things that could be wrong. then once you are logged in and try then it tells you the custome message. but i would like to make a more concise original message for both.

Any exp with that?
Thanks!!
