You are not required to add a link. Some may ask, if you remember...great. If not, no worries. Simply tell them you don't remember.

In some cases you should not put a link for example, any website that offers illegal designs... do not put a link to that site and do not even mention the site in your post. We remove all posts that have links to illegal sites.

When I download designs, I try to always add the digitizer or website name to the design name if it is not already included. Then, if and when I finally get around to using the design, I can give them credit or ask questions if I have a problem. Not much help for designs you have already downloaded, but you might give a thought to doing this in the future.

If you also downloaded the picture/photo of the stitchout, you can drag-and-drop it in Google Search box for Images. USUALLY, that will give you where the picture can be found, which will also have the digitized file/designer/website. Hope you fine a few this way. SOMTIMES just a short description of the design in Google will find it for you(and select Images). Even if you don't post links, you might want to know for yourself!

To help avoid this problem in the furture, and if you have room on your computer, save the original file in a folder just for the originals. Then rename them.
