Forgive me if this question has been asked recently, but are there a lot of TER users in Europe currently? I have been spending more time overseas now that it is possible again, and was curious about active users of this site outside of the U.S/Canada.

Many of the reviews posted in Europe are by visiting TER members from the US, which you can often tell by the small differences in the regional terminology used in this business.  My own conclusion is that there is a greater percentage of customers in Europe who DO NOT write reviews of their experiences, judging from how busy many the ladies are that I have seen compared to how many TER reviews they have.  There is no way to know how many members there might be that READ TER reviews but don't write them.  That number could be huge, again judging by how busy the ladies are.  

That all makes sense! Appreciate your insight

London is really one of the best cities to travel to. There is nothing that you will not find here to be honest!

only because I recognized Sisi.  Good choice.  Great gal.  

and it's a pitty because after BP crash I really miss other option, but I don't see TER very popular, at least in southern europe like Spain.

Used adult work in UK. Went fine they were indies.
