Seashore is now on the App Store !!! Please add your positive review there. Also, if you use it for your website, business, whatever, giving credit to Seashore and a link to the App Store will go a long way towards making the project survive and prosper. The current version requires 10.7+. If you are on an earlier OSX version, I suggest downloading the 0.6.6 binaries from seashore.sourceforge.net. Most likely you need to download the "hfs" version in order to open on an older Mac.
