Does one have to join a swap to see the various offerings for that swap?

Can everyone see the master lists of all various swap participants?

Once trading for a swap begins can anyone other than that swap's participants see the lists? the update recent activity for that swap?

Can the swap tool also accommodate plants 'for sale' or 'at cost' if allowed in that swap?

What options/functions does a swap host have available or see that a general participant does not?

What is the current limit on number of words allowed in Comments column before it goes to ?mark? Can we use a hyperlink in Comment column?

Is there some way I can get my available list in some sort of order (alphabetically?) For istance all tomato offerings together?

Thanks in advance for all responses. Swap On!
