for me is the community function where u can create multiple site for each community.
Because currently i'm doing project for an organization which have multi department, and each department can have their own site/portal. So this community function is the core for this project.
Second, is the personalization and drag and drop (igoogle style). every time I do a presentation to my client, when I show this function, they all like "Wow". hahaha
third, of course the standard portlet support (jsr168 and jsr268), easy for me to do some integration with other application.
Other, out of the box prebuilt portlet such as forum, blog, web content really make my life easy
one more requirement from my client is web hit analysis, liferay dont have that function, but after google around, i've found Piwik, the function and gui just like google analytic. You can see in the image, i use the Piwik graph plugin and embed it in the portal. look pretty neatÂ
another tool u can use is woopra. u can refer it here.
so far i know liferay use google analytic and all u to do is just key in google analytic id.
btw thanks for the info.
for media files, i think u should try searching to liferay forum.
