Good basic AMS but little customization
This AMS is good for small assocations with a standard membership structure. YM is the base model under Community Brands selection of AMS systems. As with any AMS system, it should meet 80% of your priorities at a minimum. For the most part, it's a decent AMS in an all-around aspect. My organization does not have a traditional membership model and that in itself is a challenge to manage in YM. However, the good things are that the interface is fairly easy to use, finding some things has taken repetitive questions to my colleagues. They are working towards improvements with email marketing module; however, the interface still seems a bit clunky. If you have a more advanced use of email marketing, you will more than likely stick with what you have. One thing is clear overall with YM that the content management is not as good as other systems out there (you might be better off with a separate website in most cases).
Integrations with other Community Brands products seems better than those NOT under their umbrella, which has caused some headaches for us and requires us to look within CB for better solutions. So there's that. Depending on how you look at it, you may want all your eggs in one basket...or not.
