I think that the reason they used the term "working with" versus a more specific term like "partnership" [which is absolutely outlawed by the SCYSA] or "alliance" [which seems to be allowed, but may be fraught with questions] is that they're being very careful. However, it seems clear from the text above that CESA wants to "work with" CRSA...probably in the exact same manner as described initially.
My guess is that this club will be "working with" CESA as well given their club name and the people participating.
I'd be surprised if they are much more specific than this in the short-term; it seems sometimes the more vague you are the less you can be attacked.
