List tips/reminder

Create something like fortunes? A data.frame/vector with some tips/comments?

Remember to first download .md5 or small files and then download the big ones.
It is easier to check if the download has fully finished

```bash
rsync -avhH --bwlimit=20m --max-size=1.5M --stats --info=progress2 remote local
rsync -avhH --bwlimit=20m --stats --info=progress2 remote local

```

No file, test, or entry point is named. Start by locating how this R package currently exposes data frames, vectors, or similar collections, then review the proposed rsync tips and determine how the completed reminder list should be accessed and checked.
