How to add sets to my collection?
Simply search for a set and use the “Add to your collection” box next to the set data. An account is needed for that. If you already have a list at our buddies from brickset, you can simply export it and import it here. Just use the upload form below the set list. Or if you have an Excel file, restructure it to a compatible csv or txt file for proper import. A sample csv-file is provided in the upload form.
