If you've found the Plugins Index [accessed through the SCF Resources > Plugins menu above] then you are all but there. Use your Browser's Search tool [Ctrl+F ?] and look for Curvi it WILL find it... It's by Fredo - so narrow your search to his plugins, if you are still challenged... Click on the link and it opens the tool's thread... go to the first post in that thread and there are extensive download and usage instructions... Do NOT overlook the requirement that you also need a FredoLib installation to use this tool... after getting the tool get the Lib, again carefully following the instructions on downloading and installing that too...
