I read something about credits being giving away but on respectable basis. Can I barter for credits?. I got domains names in exchange or softwares. The reason why is I cannot use Paypal and need 10 credits to get my domain added.
Credits have only been given away by individuals who have run contests, like at http://engtech.wordpress.com, and very rarely (like, a handful of times) by staff to people who have worked very hard for WP answering questions in the forum, etc. I got a domain upgrade after I’d become one of the main forum answer people and kept it up for six months or so.
I don’t think WP.com needs domain names or software. They’re pretty well set up.
