So correct me if I'm wrong, but my understanding is that the services listed for a provider on TER were put in by clients when they write reviews. But am I correct that on P411 the services that a provider has listed on her profile are ones that she herself put down?  Thanks

She may also have an option to hide or show services on her profile.

on TER and P411 is worthwhile.  They really ought to match closely.  If there are big discrepancies I want to do further research to find out why if possible.  The TER profile is created by a provider's first reviewer.  If she offers a service he did not participate in, then he may have left it off her profile info.  But if her P411 profile mentions an "activity which she enjoys in private" but her TER profile says she does NOT offer that service, I'd want to find out why before asking for a date with her.  I'd pm her TER reviewers and ask for clarification.
