If I would like to upload a worksheet, how this can be done?.

Example: in the conference "Questions" click on "New topic"
that will bring the line menu up there,
click on "trombone symbol" ... upload a new file,
double click in the work sheet in your system.
Finally, click on "Upload", then "Post" below.

You can proceed same way in any of the conference [Samples, Bugs ...]

Cheers, Jean
