1) By now, you've probably updated your profile. I've added some new fields there. You may have to set your avatar again.
2a) Some users didn't migrate correctly. Interestingly enough, mine didn't. So where you see
2b) Polls don't seem to have migrated properly either. Sorry many of those are gone. Apostrophes don't look right either! Oh well.
3) Go through your profile into preferences and private messages. There are new settings having to do with when you want email notification about different things. If you don't set this, you won't get emails at certain points.
4) You can private message multiple people at the same time. That creates totally private conversations. But if you delete that PM from your profile, I think it's deleted for EVERYBODY who was part of it.
5) Topics can be rated. Ratings won't show until 10 people have given it a rating.
6) The W2S side is still being built. So you'll see that added throughout the day. You'll need to be a paying member or in the free trial period to read, post, vote, upload, or live chat.
7) Chat room(s) are located by clicking GO and then "Chat Rooms."
8) If you want a certain icon for your post or reply, click the box NEXT to the subject when the window opens for your post or reply. Right now, there are very few. I'll look into adding the old ones.
I'll post more here as I can give you more tips on stuff.
