The concept of being able to upload your own list of species to report on is pretty much the same as what is called a "rucksack" in Recorder 6. Recorder 6 rucksacks don't have to be taxa lists (they can be lists of locations) but in practice species lists are probably used the most. The benefits of using this somewhat obscure term are that anyone familiar with R6 should have an idea what it means which I would hope would include most "power" users of the Atlas, and it is unlikely anyone will misunderstand and upload records as seems to have been the case with "species list". I always thought the term rucksack had a nice ring to it, with pleasant associations with being out in the field. However, being jargony probably would also limit the number of people who create lists (is that necessarily a bad thing?)
