I seem to spend my whole life re-licensing EPiServer sites during development, then again when it gets moved to stage and finally production. Each time I go to EPiServer's site and can never find a simple link to generate a licence and always end up having to go the download area, re-register my details blah blah blah.
Anyway here's the link I should have been using - and it's now firmly bookmarked!!
