Thanx for an answers, Alex

Some notes if you don't mind:))

1. This functionality is disabled by default in Dolphin and we removed it in UNA

What possible reason can be to do that?  Everyone of us have in Friend-list family guys, co-workers, school mates, girlfriends, lovers and pool-partners. All of them have to see my fishing weekend pics or alco-party blog??  Why that? Why to choose something worse if you already have better solution?

2. Closed group/event - anyone can find the group and see who's in it, only members can see posts

Maybe you're  right and there is an option to post smthng in group in closed manner. I can't find it yet. Everything posted under PUBLIC going to be PUBLIC, open for all. Something posted under FRIENDs  going to be non-visible to members which are non-friends of topic-starter....

3. There is a field with auto-suggestion drop-down where you can enter as many profiles as you want. You just need to enter several letters of invited member and then select.

Yeah. Let's invite to our "open air rave picnic" event, say, 100 men. In this case you (and it'll be on you, Alex, I don't going to do that :)) need to do in UNA way "enter letter-select-accept"x100 times!! Instead FB way "checkx100-accept once" You really want to ensure us that current UNA way is better than global check-boxes list? Let the list be site-long, or ABC, or friends only by radio-button - very good idea, But give us this option, why we need to work hours on invitation that takes 2 mins in FB???
