You can create a guestbook with
www.slide.com to show it as attachment for a message to friends. Here are some screenshots to clarify this process.



To copy guestbook script (that shown after the label 'Embed') from slide.com to Welcome app you can use following combinations of keys:
1) Cnrl + A - select all
2) Cnrl + C -copy selected text
3) Cnrl + V -paste selected text
Please note, that you need only part of the script, so you need to copy it to your text editor, select the part between [embed] and [/embed] and then copy to application field 'Attachment:'. Then click "Save' to save it or "Notify" to save and create activity update.
Here is example of the script (please replace '[', ']' with '<', '>' - square brackets are used here due to restriction of this text editor)
