We do not have such a widget. You could always use the template display function that puts the data into the stats area of the forum which is:

sp_NewMembers()

You can find details of the function here: http://codex.simple-press.com/codex/api/template-functions-and-the-api/display-template-functions/common-view/sp_newmembers/

That would be a nice widget to have… 

Thank you. I have to say I’m quite surprised it doesn’t exist. It seems like a pretty basic one. Is there a procedure to ask for a feature?

but the template tag is easier to use and more versatile than a widget…

we have made note of the request (first time) but we tend to do template tags more than widgets (widgets have to call the template tag anyways)..
