I like the site, but certain navigational actions like going to your own profile or browsing based on queries require more steps than it should. Still, this is a fantastic resource for finding pen pals and I've had great success with it. What I'd like to see implemented is some way to more easily find people with similar interests.
I am in an awkward age bracket for finding pen pals (85) but this organisation seems more likely than most to be able to meet my requests. I like the international dimension..
