That site has been a fantastic resource for me and the work Daath/Lars put into it is very much appreciated. Among the dozens of DIY recipe web sites out there, this one is king!
For those like me who stopped using this site after moving to mixing by weight:
You can make the site use grams instead of drops in your profile.
You can also set the weight of each flavor in your 'stash.'
An online repository like this makes so much more sense than an offline recipe book IMO... Though it could use some UI work and more user interaction/voting.
Is it down?
