well I guess whatever you do kady still if they wanna join they'd join and you'd never be able to know that they're not BCM students, right?
So I guess those who says that they are outsiders "if i may say" and still wanna join are accepted somehow ... well I really really dont know?!!!
lets see:
1- they'd always be able to register and participate without us knowing them ... that is if they wanted to!
2- those who admit it i think somehow deserves to join!
3- still and after all its BCMF and its ours only!
I really don't know ....
and about letting guests watch

well kady then what? what a difference would that make? you know other forums do this inorder to let ppl explore their site (sort of advertisment to the site) so as they'd register! so I guess when you allow it well I guess it wont change a thing! they'd also be able to register! and I don't think they register to watch .. they register to participate, right?
i just got this idea...
you can make a field in the registration proccess in which the guest should tell wheather he is one of us or not* and then members whom are outsiders should be registered and only another new MAIN branch would be available to them while the other main branch would be for us only "BCMs

" altogether with the other branch ... and topics of entertainment section I guess could have a link with that branch "or simply you can make shared topics!" that are copied to the other branch and participation are visible in both branches ...!
you can also start serious topics there ... we can tell ppl about it and they join and the site'd enlarge more and more! with us having our own private place on the net

* we could add a question here that only us could answer

so that no cheating is possible

it could be of multiple choices about 10 choices with two attempts are allowded for a single Ip and then the ip wont have access for 24 hours and the question should be changed from a while to another ... hard job kady I know but .... it'd be your job

hope i wasn't that long but its all for your baby kady
TAKE CARE my friends ...
