Hi there - I assume you are using the web not the iPhone? And is the problem that the map doesn't remember the last location you chose (when you were last logged in)? The location determines which Sparks you get (as well as other things) so let us know if this is an issue - you can email us on contact@streetspark.com

It depends where you are and how compatible you are with other users. Unlike other systems, we don't just show you everyone, but only the relevant matches. Also it depends where you are based. Main cities are best.

Yes and that's where we're based. Based on your other comments Gerard you are on an iPod Touch. The issue could be with location tracking as the Touch doesn't have GPS and instead uses WiFI triangulation. Depends on signal so back to my point above as to get extra Sparks you need to Ignite or Extinguish current Sparks before receiving more. Have you actioned all current Sparks. If so please use the app feedback feature as it gives us more info about potential issues than we get from posting it on website (and thus we can diagnose the problem).

Also to note re the original reported problem, yes the app will automatically update location based on new positioning but if using the website you need to update location manually (if you want to). If you Ignite and don't get a response to it, it is possible (although hard to believe I know) that the other person isn't interested and has ignore it or Extinguished you...
