I'd like to have the ability to get more data on recent logins. Currently, the dashboard displays "most active members" but I think a "recently active members" feature is equally if not more useful. I'd also like to be able to see more than just the top 5 results for these categories.
I think this would be beneficial for monitoring campaigns or promotions. Right now we are trying to get members to use the features of our new site or just log in at all, so if we put together a promotional email, for instance, "The top 5 things you can do on the new website" then we could see how many people logged following that promotion.
We do have google analytics installed, but I think this would be more targeted.
Also, I'd like to easily see who hasn't logged in recently or at all to target members at risk of leaving our club.
