It might not be anything, but just in case, I thought I'd report an issue I just had in case it starts happening more often (it could have been coincidental, if something was being worked on the moment I posted it).

Someone posted a note to me on my profile wall, and I had no trouble clicking "View Conversation" and writing a reply to him. The problem came when I tried to post it. It claimed there was an error, but didn't list what the error was. I clicked "Okay" which cleared the "there was an error" message and the "Okay" button (those appeared above the field where I'd typed my reply). It didn't seem as if anything had happened because my reply was still sitting there waiting to be posted, so I clicked to post the message again and got the "you must wait 30 seconds before posting again" message. I checked the person's profile in another window and saw that my message had actually posted.

Sorry I don't have any screenshots... I didn't think to get one while I was checking things to see if I could get it to work.

And here is the 2nd part of this post... more of a question. I'd noticed it before last week or so when I posted a message on my husband's profile wall. It says that our messages are moderated along with our note. Is that going to stay?
