Bookmark Converter is shareware, and if you like it and want to keep using it after 30 days you should register it.
By doing this you will support the shareware concept and upcoming versions of the program. You will also get free updates of Bookmark Converter forever, i.e. it's a lifetime license for only $16!
When you register the program you will be given access to the registered users mailing list, where you will get special info and news, and of course also immediate notification of all future updates of Bookmark Converter (if you don't wish to receive these mails anymore, you can of course easily unsubscribe yourself at any time).
So, now that you know all this, maybe you would like to register
right away? :-)
