Helps and guides
If you are a project administrator, see the Administrator-guide for OHWR.
If you are a OHWR user, see the User-guide.
Please note that you only need to register and request membership for a project if you need write access on the wiki and repositories. Read access is universal. You will not be able to access more material by registering. Also, subscribing to mailing lists is independent from OHR membership.
The guides above should cover most of the questions you might have when using the OHWR site. You can also browse the Redmine Guide for a more general guidance. (Redmine is the software used for developing this site).
