There is an issue with the 
Scirra Twitter account as it has been suspended by Twitter.
Anyone know what this issue is? Was hoping to contact them regarding the Admob black screen/Phonegap build fail issues.
It has been https://twitter.com/ConstructTeam/ for quite a while.
Also, they advise not to use Twitter for support purposes. The correct place for support is on this forum.
