I'm glad you posted this, I was wondering how the ranking system worked too, as I jumped very quickly to somewhere near 300...now I know.

And as soon as you need to take a few days off or are not as active etc. it will jump back up. I was the same way and had a rank in the 120's and today I go in and I'm back at 5600. Don't focus on Member Rank, focus on learning how to make money. (I am. (focussing on learning that is, no money....yet)

it means you participate and contribute, it's cool! :)

Ah, I see. I knew it had nothing to do with my sales!

It's the fact you are using all the things on offer. Posting a job, starting a blog, going on the forum... all this adds to your member rank... :)
