Hello,
Just a few suggestions – nothing particularly revolutionary, but to avoid mistakes with dates, times, etc. (and any unpleasant surprises), it would be a good idea to display the future date and time in IE as a confirmation.

Thanks

+1 une confirmation est demandée quand tu acceptes un i-e déjà posé par quelqu’un mais pas quand c’est toi qui choisit la date en 1er
