1. Is there any way to get info about location and show it on the datagrid? Right now the app shows only the registered user location, but it's able to catch the location using IP service and even show it. Thoughts?
No, it's ASP.NET Profile Provider limitatation. Else it'll be unbearably slow.
It's up to Jaben and the problem exists for years.
2. Is it possible to add a new feature and group all connections by IP? It should be optional for sure. But it would be much nicer if we could get the number of connections in front of every IP address instead of tons of same addresses spread.on the entire datagrid.
No, because NATs still in use. We can't identify a user's uniqueness for sure. if you mean guest - this is a known problem. No need to display pleasant, but faked data. But YAF is an open source and you can easily modify it.
