The greatest achievement we have made in Admin Support Services is the establishment of a super user community. Each major area of the business or each main country has its own super user. They serve as my front line support, train in their field also they serve as my super sounding board to get a good bouncing board. To top it all, they are good customers of Salesforce and are under continuous communication with other customers, who leave priceless feedback and tips on how to better the product. Being a Solo Admin may be a wee bit restrictive at times, there is less exposure to products, features and best practice.
