Hello! I am new to this site and looking for some advice here.

You've spoken, we've listened!  We've opened up private messages to allow any user to send any other user a private message.  However, we've also added the ability for a user to choose to only allow private messages from only their friends, if they wish.  We've also brought back the ability to block individual users from sending you private messages.

I cannot delete an old blog or even a comment.

I went from having emojis to NOT having emojis. Huh??? ~cue head banging emoji~
