Beware though.
Just a warning for you..
People at Zuken also have membership to that group, so do NOT actually mention any illegal hacking etc details as they are watching.
You do not need to actually be a maintenance payer to join or use it however there are many people on it that are because Zuken could not be bothered to see that an email forum was the best way to go at the time.
There is not actually a lot of mail going through it, bit stagnant really
but thats because the users are not posting.
Feel free to join tho...
