A user has the option to choose a gender, man or woman. It is optional, but once you made a choice, you can't undo this. I have editors who don't like their gender to be shown or don't want to choose between a gender. How can one undo the choice once made? Could there be an option added like 'netral' or 'other'?

Wow. That’s a quick feature implementation. Thank you. Will test it soon.

Sorry for my late response. I didn't have a chance to test it before. But it's a nice solution. Thanks.
It didn't gat a chance to test K2 dev. thoughroly on other aspects. Is it safe to install on a production site, or are there specific aspects I should take look at first? In other words: what else has changed?
 

There's a bug in this dev release. When an article has pagination, the url changes to localhost: https://localhost/index.php?option=com_k2&view=itemlist&layout=category&task=category&id=439&Itemid=371

On my live site (where I haven't installed this version yet) pagination in an article doesn't work. I stays on page 1, weither you click next or use the dropdown menu. See: www.ugenda.nl/recensies/theater-recensies/item/12144-9-x-theater-om-de-zomer-mee-in-te-gaan

Something is strange: if I have sef URL's turned off (on my test server) then I still get the localhost error. If I turn the nice url's on, it works...
