I have been trying to add a link to an ETL site as an external link on the ETL definitions page. The external link I am trying to add is to a site that contains a large amount of information about ETL past and future. The site does however sell a report as well as providing free information. Is this the reason that the external link get deleted every time I try to add it? It is not my intention to Spam, but I do believe the link adds value and I don't understand why somebody called MrOllie keeps deleting it
