Well, there's bad news and good news, Padfoot, followed by more bad news and more good news.
The first bad news is that all the Ravenclaw Quidditch places are full - but the good news is that the vote regarding replacement of inactive members Quidditch positions - located at
http://broomsticksandowls.com/forum/viewtopic.php?t=797 - seems to indicate that about a 4 week inactivity period should be allowed before an inactive member's Quidditch position can be made available to another member. Ermintrude2003 hasn't posted on the board since 3rd January, so her place of Quidditch Chaser is technically available now.
However, the next bad news is that Bren Creevey did ask for a Quidditch place in April. But...Bren hasn't posted for over a month now, so the final bit of good news is...
You're now a Quidditch Chaser for Ravenclaw, Padfoot!
