The wiki is just a showcase site you'd have to still link to the Exchange or a File Share site (I use https://www.simfileshare.net (and I have it set up that you don't have to leave the wiki to download)). So you can totally use the regular Exchange and still showcase on the wiki.
For me I am migrating fully to be TS3 exchange free because last I checked it said my studio was full (and I don't want to delete) and if/when gawd forbid the original exchange is retired I want that piece of mind that I am already fully backed up elsewhere :blush:
Edit: I'd recommend just trying it and if you like it enough when you have time migrate over. It is no pressure and you can do as much or as little on it- I made it for us so I want it easy and simple.
