And you'd omit all non English, which is OK is that's what you want. Personally I like the Polish girls so I want them included.
Do two searches. One with first language English, one with first language Polish?
It's flawed I know, but some users won't see foreign "skanks" so it may be a way to rule these girls out of possible punting searches. Personally, I'm only interested in English speakers as I enjoy a bit banter during a punt that I don't find with foreigners, never been with a Romanian in the uk, but shagged a couple in hamburg brothers, not my scene.
I've only got 8 pages of girls in the proximity I'm willing to travel though, so it's not the end if the world to wade through that small selection. The Romanians are easy enough to spot!
