So, how Did I go about it?
- See the bookmarklet below? Drag it to your bookmarks toolbar.
- It automatically selects all your friends and you can now send the invitation!
Hey, you may have to repeat this process a number of times depending on the number of people you have on your list. I tried it on a fan page but a friend also said it worked for event invitation. In case you have a facebook group too, you can try it and let us know if it works.
