Changing skins (Sage to Ninja or something else)?
Ning To Jamroom
#1 Choosing a skin is based on personal preference when it comes to style and look of the skin. Some skins have some built in focus, but for the most part, they all offer the same things as the modules are what run the features.
#2 All skins are free. There is no cost to switch skins.
#3 We always recommend users create dev sites for testing and development. You can do this in your hosting settings. I recommend you just create a sub domain like this dev.yoursitename.com with your site name being your current domain name.
#4 all the skins are pretty much the same. It's really just a personal preference. Some will require a little setup and this is why we recommend a development site.
#5 with a dev site you'll have a lot more confidence in your choices.
