Create a Facebook support group
Please create a Facebook support group that could be at least monitored among the RS staff. Jimdo did this and it is great! They still have normal support but for quick questions its very fast. The big benefit is other users will answer questions also so its a win-win. Your customers get tips and answers from multiple users as well as your support staff in a much quicker manner and your support staff can share the answering of questions and have the (free)help of the RepairShopr community. Check out Jimdo's, I've personally used it and it's been great!
