I was hoping someone might be able to help with this…
I have someone who has bought one of my Tumblr themes and is currently using it on one blog. He has asked if he can use it on more than one. Is this covered by the regular licence or would he need to buy and extended licence?
For each blog s/he needs to buy another regular license. So if he runs 5 blogs and on each s/he wants your tumblr theme on it s/he needs to buy 5 regular licenses.
