Well...you can integrate more or less any forum system (not sure what Zuzanas is) -> just be careful to choose something that isnt a complete wormhole of security bugs (which rules out most php forum
) ... aside from that any of the big ones could be styled to fit into an Elevated template smoothly
Anyway...the main thing to consider aside from that would be: WHY? Whats going to happen there and who´s going to make it happen ?
Ie -> what is going to draw the members there and make it an asset for them?
- If it is just a support forum where they can see what others moan about its better left in private
- if its a forum where they can post their own stuff its a 2257/copyright nightmare
- if there´s nothing but announcements and random chit chat it easily becomes an abandoned wasteland nobody uses
But...if they can sometimes communicate with models in there, maybe there´s even the odd live chat that´d pull them in. If there´s contests, votes and giveaways they´d like that too. If there´s more behind the scenes photos and videos, maybe little selfie style shortie videos from the models on the way to the shoot or a few nice shots teasing from their private bedrooms for upcoming movies etc etc ...
Basically -> you need extras & actual things to create engagement...reasons for going there
