If you have accidentally created two accounts and want to transfer your recipes from your previous account into your new one, you can do the following:
1. Log into your old account, and let it fully sync and download the recipes from that account.
2. Go to Paprika's Settings -> Export, and export a copy of your recipes to the Paprika recipe format.
3. Log into your new account, and let it fully sync and download the recipes from the new account. (The recipes from the old account will be removed during this process.)
4. Go to Paprika's Settings -> Import, and import the file you previously exported. These will be treated as new recipes and added to your new account.
