How do I clean out my old Messages?

There is two ways of going about this. 

1. You can Archive All, and then go through and unarchive the ones which are still current and/or important.

• To do this, just click the three dots in the top right corner of your messenger screen on MorphMarket and tap "Archive All".
• From there click the "Inbox" menu n the top left and go to your Archive. Open the important ones and use the "Unarchive" button found in the Actions menu to return it to your inbox.

2. You can go through the unwanted messages and use the "Archive" button in the Actions menu.

The quickest method will be dependent on whether you have more wanted or unwanted messages.
