I suggest that we add the ability to renew an expired trade when you recieve the mail that states the following:
"Your trade has expired - your items, silver beetles, golden beetles, and lionesses have been restored. Your trade was called (name of trade).".

I believe that it would be easiest to put the option here, in the following format:

"Your trade has expired - your items, silver beetles, golden beetles, and lionesses have been restored. Your trade was called (Trade name). Would you like to renew this trade? If so, click the button ( location of button) [Or Click here ( and a link)]".

However, There could also be a button on the den page, maybe, if that is preferable.

If you support or choose not to support this suggestion, feel free to leave a comment why, and have a wonderful day/night!

Suggestions:

When you click the button, it takes you to the make a trade screen with all of the previous item/lions/currency, or, available previous items/lions/currency, selected, so that you can edit the trade in some ways before re-posting.
