Bare in mind that CCM is a mutual aid community, all answers on the forum are provided by volunteers who give their time free to help solve issues.
Hence we request that CCM forum users show mutual respect. Therefore, when asking for assistance, please be courteous, as for elsewhere in similar circumstances in every day society when asking for help. (Usually, how would someone ask for help? i.e. please, thank you, appreciate, grateful, etc.)
Being courteous will also increase your chances of getting the help you need.
