[opencms-dev] Is OpenCms suitable for sites with a lot of user interaction?

[Bas de Nooijer]

I'm considering to use OpenCms for several sites. However most of those 
sites have a lot of user interaction for example personalisation, user 
comments per page, even an extranet with a file storage for each user 
etcetera.

Is OpenCms suitable for this kind of application, and are there examples 
of it? I've been searching around quite a bit but I can't find 
comparable examples or any documentation about creating the kind of 
functionality i want.

Thanks,
Bas
