I have so far downloaded three arrangements for my little choir from ChorusOnline and found their service to be very efficient. Not only that, if you do encounter problems, as I did (my fault entirely Must add!) someone responded very quickly to my query. Always a worry when downloading things from the internet that there is none to follow things up with but this wasn't the case. Thank you very much for some great resources!
Strengths
Able to contact someone and very quick response to query
