I need to set up a collaboration Tool (online) for an NGO.
I loved the features of Liferay Social Portal, but Java is too complex for me to understand. Does anybody knows a php alternative for it? Features the same as Liferay Social Portal (i am not allowed to post links) (maybe, without the Office integration), but must be able to set non-intranet pages for guests (wiki-posts) and a custom frontpage.
Every help is much appreciated!
