Just to let you know that Greenfoot 3.8.2 is now available from the Download tab. We inadvertently introduced a bug in 3.8.1 last month that prevented you sharing new scenarios to the website (or modifying the thumbnail screenshot when uploading a new version) -- it would just sit there and seem to process forever. Installing version 3.8.2 should fix this bug and let you upload again. (While I'm doing an announcement, we've also adjusted our spam filter to try to eliminate the wave of spam that hit the forum over the last week, and so far it seems to have worked.)
