I'm relatively new to Umbraco development. I'm needing to create a discussion forum and was looking at SimpilyForums and Dialogue add-ons for my solution. SimpilyForums was going to be too basic to fulfill the functional requirements so I've abandoned that for Dialogue. I noticed that both of these add-ons haven't kept up, compatibility-wise, to the latest versions of Umbraco. Umbraco v7.1 and v7.2 are the last versions that these add-ons were tested to function at 100%. Are there other 'forum' add-ons for Umbraco that Umbraco developers favor? Does anyone still run SimpilyForums or Dialogue on Umbraco v8.1 with no issues?
