I'm a bit of a noob with php but what ive seen is that it does not enqript the password files.
there website is down and the last update is in 2007 so don't think you ever get anny support.
some images dont load (think there linked from there website)
you can not enter the normal website under the admin name, jou need to make a new acount.
Its verry easy to install (got only one error telling me i have to make a folder).
lots of cofigs in admin.
it does what it have to do.
I don't think its safe but it works
