I have planning on setting up my site using Xenforo on a rather new but well reviewed host called Digital Ocean. However they don't offer proportionately growing transfer data as other sites. So in case I need to transfer from it to another vps host, do I need to reactivate my license? Or I just stay put about it? Are there any issues I should be careful about when changing my vps provider? now that I'm starting to pre design skins for my forum, does Xenforo support multiple skins/styles for different sub forums? Thank you very much!
