Pamphile Roy and myself created a new “openturns” tag on StackOverflow in April 2020.
This allows to tag questions which are related to our favorite software, e.g.
Posting a message in the question/answer style is also an option:
Please consider adding this tag to you question if this is relevant and/or add it to an existing question if an OpenTURNS scripts may fit the topic (send me an email if you cannot add the tag: this requires a minimum level of “reputation”).
In all cases, StackOverflow is not a forum, so that discussions may still be posted on the current forum.
