2 questions about ubuntu + offering

[Xan]

Hi,

First of all, thank you for reading my post. I'm a desktop user and perhaps 
this is not the best mailing list to put my questions, but I think that it's. 
Sorry if some are obvious for you.

I have two questions:

1) I tried Hoary live-cd array-5 and when I put usb key, it detects me the usb 
key and mounts me it (I tested previous versions and it's the first that do 
correctly). But I don't watch any user friendly way to umount 
that, ie to leave safely the usb key.

Is it a way to extract usb keys when ubuntu mounts that, without login as 
root?. If don't, I think it's a good thing to put on ubuntu, overall for 
novice users as me.

2) In Debian ftp, there is a link to unstable version. (unstable points always 
to unstable version). In ubuntu it does not exist, isn't?. Could you put 
unstable link to unstable version (now Hoary, then GrumpyGroundhog, ...)

It's useful for people who want to be always in development version.

Finally, an offering: I have a partition avaliable for testing ubuntu version. 
I calculate that I could test three or four releases of development versions 
(at finally, I boring to do that and I want to stabilize my system ;-)).  I 
have no production system, so I could do (I have debian in main partition as 
production system and another partition for trying distros).

Now I have ubuntu installed in that partition.


So, If you want that I test some critical releases, I'm charmed to do that.


Thanks in advance,
Xan.

PS: Perhaps a good thing is to put some reference into wiki of betatesters (as 
gnoppix do into webpage)
