Thanks. raco link -d <collections-dir> is working, that is, my collections are found, although I still have one little problem. The precedence of my linked collection directory seems to be lower than for the built-in collections. With the explicit collections directory setting in drracket I'm able to set the github directory higher, which allows me to shadow built-in collections. Now my code is loading the built in collection, rather than the replacement I'm using.
A workaround could be to rename the replacement collection (net), which is not a big deal, but inconvenient. Please let me know if I'm wrong about this. Otherwise, is there a recommended way to shadow a system collection? Thanks, Erik.
