Guilds ? Clans? friends list?

Wouldnt mind seeing these so i can easily chat to my friends and easily see when they log on|||looks like blizzard is a huge supporter of guilds, clans. i hope /f l stays in and maby i can use the same account name for d2+d3 (like you can for other blizzard games)|||I just hope they get rid of the "whisper to everyone on your friends list" command, or at least let you ignore people using it. People using that to hold conversations with a single person (and thus spamming my screen with irrelevant junk) were incredibly annoying.
