Block first timers from Party Finder!

[Ashkendor]

Make something like Thordan Practise Party for First Experience impossible since there is no df for it. Forget it.

I think you're responding to the thread title (granted, the title is a bit misleading but thus far there's been no luck getting it changed). OP isn't asking to exclude first-timers from the PF completely. What they're asking for is a flag or click-box or some such that would allow a party leader to prevent first-timers from joining a party made specifically for the purpose of farming. This wouldn't do anything to prevent those without clears from making their own parties for learning or clearing - in fact, it would probably encourage it.
