Is it worth the time investment to go thru and request a bunch of these one-off quals for different surveys and such? I know I've done this before and it doesn't seem that I've gotten anything back. Has anyone had experience with getting these quickly and automagically being qualled for something else that you didn't expect, or that was possibly hidden previously?
1) No I think your time would be better spent looking for live stuff and requesting them as they pop up
Not really worth your time. Most requesters don't ever check or receive those requests. Example: One time, somebody used a script to automatically work through the qualifications and request all the quals they could. They may have picked up a few, but it wasn't worth it.
Glad you asked, was just doing this myself as it seemed someone suggested this. Thanks for your help.
