A new package called -adolist- is presented. -adolist- is a tool to create, install and uninstall lists of user ado packages ("adolists"). For example, -adolist- can create a list of all user packages installed on a system and then install the same packages on another system. Moreover, -adolist- can be used to put together thematic lists of packages such as, say, a list on income inequality analysis or time-series add-ons, or the list of "41 user ados everyone should know". Such lists can then be shared with others, who can easily install and uninstall the listed packages using the -adolist- command.
