That's a great idea ! I like it ! We won't have students at MuseomixAura, but "Remix workshops" will take place at Lezoux (Museomix Aura) and we'll definitely have crazy stuff invented by visitors. to share on social media.
Even though it seems more appropriate to use a new hashtag, indeed, so far we have use the #wearemuseomix for people who gets involved within the event or association.
But, I like your idea that getting into a remix challenge, people gets to "enter" / integrate the big community of Museomix ( okay, it sounds a bit cheesy....but we do like people at Museomix !!) , I like this idea very much. Why don't we combine # ? The # challenge might help to trim pictures from the portraits gallery and these ones.
So let's go for #wearemuseomix + #challenge : what do you think ?
For the #oclock : let's vote for 11am / 5pm / 8pm , sounds fine for you, doesn"t it ?
