These compliments are very, very much appreciated, especially coming from someone such as yourself. We've managed to find and squash a few bugs already, and I'm sure there are still many out there. We've also got lots of features / content / tweaking left to do, but in a short amount of time, we should have everything under control. We hope to keep getting feedback from everyone - positive or not - so that we can build the exact tools that Young Scientists would like to have at their disposal. Again, a sincere "Thank You" for your comments, steven
