There should be a [ IN GANG ] forum. Here are a couple of reason as to why this should be

1. Wars or EXP- members of the gang can spy and share stats with people they spied on just in case they could attack them theirselves or if there is a person who is done training for a little bit and want to get to a level, people who have already beat those inactive players can also post their stats.
2. It makes it easier for gang competitions, keeping track of gang member deposits, a members cry for help, etc
3. If there is something that is very important and the Leader may be Inacti. and there is a very active shoutbox, these posts will be always visible and never just PAGES AWAY.
I understand that I may not have a lot because I cant really think right now, but maybe you have something to add?

This has been suggested tons of times and has never been implemented

and as for the reason's
1. if a member wanted someone elses stats and didn't have the cash to spy as being a helpful gang member i don't think i'd mind missing a max of 60k to give to a gang mate for it
2. this is what Member Contributions and Gang Members Details are for it's already there
3.if there was a important message i needed to send to 0YeahBoy0 and he was offline i would just pm him.
we don't need gang forums, the fact you could only make 3 reasons which i have easily made solutions for just proves that we don't need to waste admins time making a pointless addition
