The 2 biggest mistakes the Siyum organizers could commit now, is:- 1) un-inviting HoRav Lau shlita 2) Having speeches in Yiddish;
Whilst none of us are big enough to judge which of these 2 actions would be worse, we are all big enough to say in no uncertain terms, that either of both of these actions will cause unforetold damage to the upcoming Siyum, & I hope & trust that the organizers will know better.
