I actually think that we have gone off track, even with my suggestions. The idea of user titles is to make people post and grow the forum and they are basically used as a status symbol.
I think that with most of them they are too complicated and a new user will not know what they mean as there is no obvious structure or order progression to the names which I think is essential.
Going down the chemistry route is also a bit obscure as this is a business forum not a science forum, the best I think would be something similar to uglydoll's idea (below) although it needs tinkering, just my opinion and I am not necessarily right
Infact I am possibly taking this faaaar to seriously
1. just window shopping
2. lurking in the entrance
3. popping in for a closer look
4. wandering through the threads at random
5. taking a closer look at what’s being said
6. browsing the posts with intent
7. getting into it now
8. really paying attention
9. taking a magnifying glass out for a closer look
10. no posts escaping scrutiny
11. starting to fixate
12. it's becoming an obsession
13. this forum fills my every waking thought
14. I eat, sleep and dream of threads
15. I am known as the King/Queen of Business Labs
16. they asked me to join the admin team!
Or something silmilar to below which has some kind of progression:
