It's been a lot of work (thank you all for your patience) but I'm pleased to announce that I have completed work on a new feature - you can now post messages directly on other user's profiles.
Effectively, you all get your own personal little forum - each profile can have multiple posts, each with its own set of replies. Anybody can subscribe to any post and receive an email notification when a new reply is made.
Want to thank someone for their send? Or just say "Hello"? Visit their profile today and create a post today!
