Before using the live chat to request help, please try using the Log Analyzer to check for common problems. Use Help / Log Files / Analyze Last/Current Log from inside OBS.
Do not ask "Can anyone help me?" or "Is anyone here?". It may seem impolite, but it's best to ask your question straight away with as much detail as possible. A copy of your OBS log file will likely be very useful. See getting help on IRC for more guidelines.
Please keep in mind that the people in the chat are community volunteers. No one is obliged to help you and spamming or a bad attitude may get you kicked.
