Also, check maxobjects.com, it’s a database of max patches.
Another good thing to know is that if you select all of the objects in your patch and hit copy, you can past the patch as text into a post. So if you look at a lot of the discussions you will see many lines that look like this-
indeed, even just pasting the text right into the patch will also work, as will selecting your objects and pasting into a text editor. that’s pretty cool.
You can also get a picture of your selected objects: copy, then Paste Picture. nice for screenshots or partial ones, it includes a bounding box with only the selected objects. Might be handy for tutorials or descriptions, who knows.
