[Mantisbt-help] Description of access levels?

[Kurosh B. <ku...@ro...>]

Hi,
 
This is a newbie question, but I didn't see any adequate information in the
User Manual, and a search of these archives didn't make it clear either:
What do the various user access levels give permission to, exactly?  (by
default)  I understand that these things can be (somewhat) modified, but
there's no information (that I can find) on what they allow by default.
We're currently using 0.18.2, if that helps, in case the defaults have
changed from version to version.
 
Also, if there's a listing of what can be modified in terms of access
levels, that would be great.
 
Thanks,
Kurosh
