There is a big button in the main menu

at the bottom from the entry page in the addon area is a small link to a form for addon-uploads - see at
http://www.WebsiteBaker.org/en/add-ons/add-ons-project/contribute.phpi think, Ruud in the Men there
i'll talk with the guys about a better link on this page, maybe as a link in the right menu
the problem at other places like AMASP is, thats a one-men-show, everything stops if he goes to holiday or in a hospital for a longer time and if everybody send modules, its too much work for only one person.
2. its not possible for me to send a updatet module, i dont know, how - and i cannot find any information about that, maybe, i'm blind - i know, its work for other people
