I appreciate: - Proposal 7 by Sorana Secu, it communicates the idea of collaboration(see X) - I don't like the choice of colours. - Proposal 15 by Vishal Battula, it communicates a feeling of joy and it's easy to remember. - I like the font and colour choices made by Ecaterina(proposal 1-2). I think that the idea of collaboration is suggested by the word Wiki, then my vote goes to Proposal 15 but I think we can adopt the font and colours picked by Ecaterina, if it's possible to make a merge :D.
