"Free" version is useless

Works well, but there effectively is no “free” version. Functionality is limited. Cannot select specific categories in the “free” version. It defaults to send “To”, “CC”, “BCC” emails to the poster and to the admin. This means inboxes of the poster and the admin fill up with duplicate emails. The only way to address it is to pay the fee for the pro version. A developer is certainly entitled to be paid for his work, but this should be labeled as a “demo” installation, not a “free” installation.
