Hi @Tee Hiett I also can't seem to find the share function on the site. Most likely this is an issue with the most recent update that was made to our answers.flexsim.com site. Unfortunately this site is a third party service so we are not able to investigate this issue ourselves. We will reach out to our provider and submit a bug report.
In the meantime you can always copy the url from your browser if you need to link to a question. If you want to link to a specific comment then it seems like you can hover over the time stamp the comment was created and right click to link directly to that comment.

It appears that this is only possible with comments and not with answers or the questions themselves.
Sorry for the inconvienience
