Zekke is sick and won't be playing in next matches (nor at anything else for that matter) for the rest of the term. Reign as you well know has quited, and so has Sangeetha but for a matter of time schedule (timezones) rather than anything else.
I myself don't have the slightless idea where everybody else is (*cough*exams probably*cough*) and you, Aph, me and Amy (and Andrea?) seems to be the only ones interested enough to be in the pitch righ now.

I can't make people quick up with the actual practice so I am advising you to do what I do: Find an old post of yours and use the edit button to try your speed against Gryffindor/Ravenclaw by trying to respond to the match questions faster and neater than them (look for the date of your edit and compare them to the player's). This will be visible only to you. Nobody else will see your result nor this does matter -this is only so you have a more challenging and probably more exciting and useful kind of practice. The Common Practice will be held as always but this new will be as well, for those who are interested.

I hope this sufices as an explanation.
