Yes, but its not as straight forward as it may seem. A module can create profile properties if it needs to, but cannot make those visible (technically you can, but you shouldn't to avoid changing registration). You would also have to check to see if the property exists first. The next problem you face, if we do a check and see it doesn't exist, what group do we put it in? (ie. Street belongs in Address)

Regardless, you still have forum specific items such as subscriptions which would require a user to manage them in a "My Settings" area. While I feel we can offload some items, this area is never going to completely go away.

I have mentioned this before, but I think an easy solution to this may be to allow templating and replacement tokens - for example, on PokerDIY, I use Ventrian's Private Messages and the Smart-Thinker Profile system. You can see how I have hacked my signature to use the ST UP profile, but it would be great if this could be automated.

I would love to be able to have my Add to Group, Invite to Event, Send Message, and use the ST UP image etc. - all this would require is an HTML block that exposes the UserID - it makes the module so much more flexible and can plug and play with other modules (core and 3rd party). I also don't think the replacement solution would be relatively hard to do for the benefit it would provide (I currently have to turn off UserLists and Private Messages on the forum as it just confuses the user having 2 identical sets of functionality. I provide a site-level user directory of poker players, and Private Messenging is not just limited to the Forums.

Chris, if you decide to look into this more, let me know and I can provide some use cases/ideas if you want?
