The truth is junior members often get promoted in batches whenever the admin feels like it, so if you have made a couple of posts and/or checked the org regularly, you should get your membership pretty quickly. Junior membership is meant as an 'introduction to the org' so you can get a feel of the place and the community and possibly, to stop people from just signing on for the tavern...

It's a title for people who have made 'significant contributions to the community', a lot of modders get the title it seems, as well as ex moderators, although senior members often become moderators too, I'm not sure what usually comes first.
