I'm also offering to help if needed (PM'd ichigo)
I spend most of my time doing stuff on Linux/UNIX systems, am very comfortable working at the command line etc. and have a fairly wide skill-set from development to general admin tasks.
(Gee, sounds like I'm applying for a job lol)
Of course, it could be the case that server/Linux maintenance is only done by the hosting provider... I can't really say though as I don't know the hosting arrangements
Anyway, give either of us a shout if any extra hands or brains are needed
