We have designed modern, ergonomic tools that are easy to understand and use. It takes little time to learn them, even for a person not familiar with Internet tools. Our tools are visual and usually speak for themselves. In case you feel lost you will find help bubbles with the tools, notes of explanations, a contextual help, and you can also refer to the general notice available on the public part of the site. Note that testers work constantly to help improve these tools.
As a general rule, yes. All tools will allow you to manage communication, information and documents in full autonomy. You should not need assistance or particular skills. Some tasks may require a slightly more technical effort, such as using a scanner to digitize paper documents, and assemble the produced files into a PDF document that can then be uploaded to the site. This type of operation can be carried out by those of the co-owners who feel most comfortable with the tools, and who can then do it on behalf of the other co-owners.
