The "Forward to a Friend" page has been removed from the site. This is an attempt to make MemeStreams a bit easier for new users to understand, by making the user interface more similar to email. You can now choose who you are forwarding a post to on the same page on which you compose it.
This change simplifies a few aspects of the site. In particular, there are now buttons throughout the site that give you one click access to the interface needed to send a MemeStreams user a private message.
As always, let us know if you have any feedback or if you run into any bugs.
