Yes, as you say the site is expanding... I think that next weekend some maintenance will be required as there is about 200 MB remaining on the server. I'll have to change a setting on OVH configuration to have 20 GB instead of 2 GB (as I mentionned somewhere else), and for that I'll have to "lock" the site, i.e. prevent any change (including comments) for one day or something like that.
Anyway I'll put this week a message on the forum and on the site with all the details, so nobody miss it
