SSMA 1.0 for Mac can be downloaded from our website for free. The actual developer of this free Mac application is iJadd. The application is included in Communication Tools.
From the developer:
SSMA - The action will let you choose the capture area through the cursor, then will save the file by name “screen capture”. The action then will open a new mail message (through your default account) and attache the captured image to it (with the subject line: “Screen capture” which you can edit of course).
You may want to check out more Mac applications, such as Enough, MailBrew or Seesmic for Facebook, which might be similar to SSMA.
