Please don't resign

I want to practise my end game. I want to practise how to do mate. I want to practise how to prevent stalemate. Even if you lost accidentally your queen, don't resign. I can too make an error and lost my queen. Even if all you have left is a king, there is always possibility to stalemate. Don't resign!

Then we have the people moaning about their opponents not resigning in a lost game. It's really bugging me how ignorant and self-centered the majority of people are.

If you can already see the end of the game, then it's pointless to actually move about the pieces. 

Yes, but I can't see the end game. Or I'm not certain and I can make terrible mistakes. I haven't practise it enough. Opponents suppose I know, but I do not. But maybe this is a thing that can be dealed in a chat window, to ask that could you please not resign...

Me or those who moaning or both? Are ignorant and self-centered?

Simple as that, set up an online analysis board (just type this in Google), set up the last position, and work your way through it.
You'll figure out why did your opponent resign. 

I suggest you get a chess engine. Set up the position where your opponent resigned and play out the game. Then you can use the engine to analyze the moves. Not everyone has a lot of time to waste on a lost game. You're right, its usually best for someone on your level to play a game out since its always possible to blunder to lose a won game!
