Contents, Flags, Users and Node views I am in the process of making a social networking web site with Drupal7. Most of the tasks are done. However, i am stuck at this issue big time. I have created custom content type, Challenge. Using the flag module, i have placed a flag, Accept Challenge, on the nodes of this content type. Users click on this flag and accept the challenge. Now to complete the challenge users, have to post a blog about their challenge. So is there any way that when the user goes to node/add/blog and begins blogging, in the title field he or she has a drop down to pick from the nodes he has flagged. The name of the title should be same as that of node which was flagged. Please advice.  I hope i am clear. If not, please tell me and i would try my best to be as clear as i can
As a workaround you could show a list of accepted challenges for each user and link them to node/add/blog with the title prefilled using the prepopulate module.

You could also create a node reference from blog to challenge, use a "select" widget and narrow the option with a view (that's a cool feature of the node reference module). In that view you limit the records to the current user and only the challenges they have flagged.
