In reply to Justin Busa.

Like other people mentioned elsewhere it would be nice to have another option - calculation to happen in background, or on focus. This is actually how it started, but I then backed to "lock" kinda widget which gives clear feedback on what is going on vs having to wait "something"

I was thinking about adding new option to underlying jquery.hashcash.io plugin to auto unlock on form focus. This should save time for folks to type whatever comment they want to type, and by the time they are done - submit button will be unlocked.

Whenever I get a chance to do it tho... Busy on more backend work for this project right now. So contributions are very welcome :)
