Guillaume-
Discussing with Olizekat I find out he had to work the night to be able to finish logos for the deadlines.
Yeah, he's trying to let his ant run all over the place. :-) I like MiWiki, I really do, but the second stage is not intended for coming up with entirely new variants; they should have been made in the logo submission phase which lasted more than one month.
I suppose other creators that have a job can't spend all their time to design logo.
There seems to be a misunderstanding here. The 10 day period is not for coming up with entirely new variants. It's for talking about the logos and making small refinements, like adding a little shadow here, making a logo transparent, making it sharper etc. If people manage to do more than that, that's great, but this is not really the point. After we have chosen a winning logo we can still talk about optimizing it, even after it goes live. We can always work on making things better.
Honestly I don't understand what are the arguments to hurry the deadlines?
Please try to phrase your question in a way that accommodates my point of view that the deadlines are not hurried.
Regards,
Erik
