Re: Running php modules in a mojoportal module?
I don't know of a good way to run php apps in mojoportal. Might be feasible inside an iframe but then its really a different site with its own db and users. Not real feasible to come up with a generic way to share user data with other apps that I know of.
We do have search, messaging is planned, not sure what you mean by files, seems like there would be security risks in allowing file attachments except from maybe trusted users. An admin can already upload a file in File Manager then create a link to it in a forum post.
