C#

1. Don't post the same question more than once especially less than an hour after posting the original question. People on these boards give their time freely and don't get paid for their help. Just because something is urgent for you, doesn't mean that somebody else is going to give it their fullest attention until they are ready. Multiple postings makes it less (rather than more) likely that you will get help.
2. Try to make the subject more meaningful in describing the problem.
3. Don't use text speak. This is annoying. You have a keyboard with far more keys than a mobile has, so use it. You're not a surfer boy so ending something in a Z is just asking for trouble.
4. Don't use capitals to try to get our attention.
