The different ranks or titles you see under peoples' names mean the following:
A "Neophyte" is someone who has just joined and started posting on the boards. After a certain number of posts you become an "Activist" and are basically just a user of the boards who happens to have more posts.
"Advocates" are the volunteer forum moderators; we are generally a group of users who had been active in the boards for awhile and who are familiar with Scarleteen's articles and inormation and the usual tone of replying to questions.
"Sexperts" finally, are the volunteer forum administrators who have control over maintaining the entire board and the members. They have been with the board for much longer than most and are also very knowledgeable about sexuality and sexual health, some work professionally in the medical field or more in sexual/health related fields.
And anything concerning the site/staff is fine to either post here or in the Staff Stuff section.
