Should you proceed beyond this number, then you'll be given the

badge (50,000).
User titles reflect a user's participation on the forum and are visible on both post and profile pages. The requirements for user titles are the following:
0 - 24 : New Member
25 - 49: Junior Member
50 - 499: Regular Member
500 - 999: Senior Member
1,000 - 4999: ScubaBoard Veteran
5,000+: ScubaBoard Guru
User titles may also be given to members of (private) user groups.
If you become a supporting member (pay $40 a year) your user title can say whatever you want it say. You might be able to have your say Divemaster without paying the $40/year...I'm not sure. You should post that question in the site support section if you are curious about it.
