In order to accommodate the large number of players on the BBO site, they have recently made a major update to its structure to divide it into two areas, Competitive and Casual. The significant thing about this for our players is that if they want to play in EBU event or those of Virtual Clubs, they need to be in the Competitive part of the website at the time the game starts. They will not automatically be taken there from the tables in the Casual section.
Login -> Competitive -> All Tournaments -> put EBU in the search box. Paul Gipson has produced one of his extremely helpful Youtube videos explaining it all in detail.
