hi pballmama & zer0fill.

I'm sorry for my late answer.

I think the permission system

GROUPS * TYPE OF PERMISSIONS * CATEGORIES

are too complex to implement their interfaces.
Have you seen news2.0 ?
I don't think its "group permission" looks good.

And piCal's "categories" is not the same as "categories" of another modules like news, myLinks, myDownloads, and myAlbum-P.
piCal's categories is defined as RFC2445.

My answer to the problem is "Duplicatable Module".
I've already made TinyContent and myAlbum-P as duplicatable.

If I have a settled free time, I'll modify piCal as duplicatable.
