Hee, thanks for the review! Its good to know that people out there think well of us!
Just a few clarifications though:
- All tutorials are totally free to view. You only spend biocredits in the downloads section.
- Submitted tutorials that make it to the main pages earn you between 100-300 biocredits. Most other user-contribution (i.e. forums posts, image uploads, votes, etc) earn you between 1-2 points each.
