Limit Community Membership on Swym Signup

Currently when you open a Swym account you are automatically enrolled in 57 communities, which is likely to be at least 56 too many.  Proposal is that on account creation, a new user is subscribed to zero communities and presented with the list that enables them to join the ones they are interested in.

Alternatively, they could be subscribed to communities related to what licenses they have (e.g. SW license holders would be subscribed to SW User Forum and SW News and Info).

This Idea would work in tandem with this one:  https://r1132100503382-eu1-3dswym.3dexperience.3ds.com/#community:yUw32GbYTEqKdgY7-jbZPg/idea:gnVn5ziuRgOod5X49H3-rQ
