Don't have permission to view 'airline specific private forums'

[passportstamp]

Long time lurker, relatively new poster though so this may be a bit of a noob question...

Whenever I try to access the EasyJet airline specific private forum, I see the following message:

"you do not have permission to access this page. This could be due to one of several reasons:

1. Your user account may not have sufficient privileges to access this page. Are you trying to access a private forum, administrative features or some other privileged system?
2. If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation."

Is it just a matter of posting more & building up a 'reputable profile' before access is granted, or are there any specific requirements?

Thanks in advance!
