Please help a newbie...

Lichtbold

to get most out of his Smugmug account.

I've chosen Smugmug because of the high quality presentation of pictures.

But: coming from ipernity, which provides community features like:
- replies to comments, lists of latest comments and replies to comments
- lists of latest uploads of all members, of friends or contacts
- faving (bookmarking) of pictures

I feel a bit lost here. Are there features like the above on Smugmug I have overlooked?

Thanks in advance!

Roland (Lichtbold)
