Text Editor string for "You can't kudo this post"

PerBonomi

Yes, there are different strings for all these scenarios. It works on the basis of keys and you can change these keys under Studio > Text Editor

li.kudos.kudo.self = Sorry, you can't give kudos to your own contribution

li.kudos.kudo.anon = Sign in or register to give kudos

For already Kudoed, you will get an option to revoke that Kudo. 
images.button-kudos-enabled.revoke.tooltip         = Click here to remove your kudo from this post

Thanks VikasB. That just leaves the one I really need, string2.

It's mainly the last criterion I need:

• You're logged in
• This post can be kudoed
• You haven't kudoed this post
• You don't have permission to kudo anything in this board/community.

PerBonomi

It may work. You need to update value for place i.e. forum, blog, contest etc
kudos.button.needs-permission.title@place:contest  = Kudo

I'll give that a try, thanks.
