Is it advisable to shorten a URL manually with cort.as so as not to “waste” characters in the message?
No. When you want to include an URL in a message of Eskup you don’t have to manually shorten URLs to “save” characters in the message as Eskup does it automatically for you if by doing so a “significant saving” of characters is achieved. For this reason, URLs of less than 30 characters long are not replaced by a cort.as URL. Moreover, if you let Eskup do it automatically, a tooltip will be shown in the shortened URL.
