Possibility to change author of content

In our community some of the first topics (like welcome post, new to the community etc.) are written by a person no longer working with the community. I wish to change the author from her to me as I am now the person our members are interacting with and I would like them to see my face on the introduction threads and similar topics.

I think it would be great if one could change author between Community managers at least, so that we don’t have to delete and repost content if someone is leaving, or log in to multiple users and keep them active to make it more welcoming for members and to make sure we’re not missing pm’s etc.

Thanks,

Mette
