It does work. Make sure you don't have any additional spaces, especially around your URL. Proboards is very helpful in that it makes any link a clicky link by default (which is kind of awesome), but that means if you add spaces around an image URL inside code it jacks things up.
One from me...if you want to get emails (or a big alert box) when someone PMs you (the default is neither of these--just to change the count at the top of the screen):
Open your Message box (click the number of messages at the top of any screen).
Select Preferences at the upper right.
Change either the emails or alert box (or both) to yes.
What a pita. I miss just being able to copy & paste.
Ok, this explains why I could not copy and paste the image I found of my wedding dress.
That's what I was trying to do too. Once I have some time to mess around w/ this, I'll have to photo bomb the board w/ pics of my dress to make up for missing out on the fun. I loved my dress!
