Search facility on UKP AND ON AW are your first port of call.
If you are interested in any particular girl, then first search on here to see what has been written about her, especially reviews.
If you find no informatiom then by all means post their profiles and state that you have tried to look for information on them, but did not find anything on here.
Asking for help is fine, simply asking for info without having carried out any background work on here tantamounts to being lazy.
