Well, nothing says you couldn't make a working replica of your current site, and then play around with it.
I mean, it is kind of silly to recommend an entire additional software combination to add onto your site just for one little thing.
However, knowing what else it can do in addition to just registration management, I know there will be something else that will make you go "Wow, I'm glad I tried this."
Here's an example. Built into the site are error logs, that record all errors within the setup. Easy to access, you can filter results, and certain 'behavior issues' happen to produce very distinct messages.
Got a problematic IP or user?
Ban 'em with the click of a mouse, and entry of a little information.
Ever wanted to add content to the WordPress sidebar, but don't feel like modifying a file?
It's possible through the block system.
I'm actually looking for some good feedback from a current WordPress user.
I made the offer to another user, and I'll extend it to you as well.
If you would really like to try it out, I'd be happy to personally assist you with it. If you can make a working copy of your site (using duplicate tables), I'll help you get it all installed, and get it themed to match your site.
In fact, if you would prefer, I can help you theme it to where it looks like your site does right now. With some new, cool stuff of course.
Only thing I'll ask for in return is your feedback on it.
I get emails from our userbase, but feedback from a source that isn't familiar with it, and a fresh perspective is a goldmine for us. Let's us get a new angle on operation, use, etc.
I took a screenshot (as I mentioned in the thread here that I referenced above) of an installation that has WordPress as it's focus. Grabbed a random wordpress theme (happened to be Senorita), and then added the setup I've referenced. I themed it to be a WordPress site, look like the WordPress theme, with some additional stuff.
