Add content on the front page
For new or occasional users, it could be useful to have some information on the front page of Redmine; for example, something from the instructions posted by Rossen on gmx-developers: http://lists.gromacs.org/pipermail/gmx-developers/2011-January/004983.html
Or the front page could contain link(s) to wiki page(s) that contain that information. Or something else. It would help get people started, and could also be used to give instructions on how to report bugs (e.g., that the Target Version field does not mean the version in which the bug was detected).
