Hi good people, those with such machines,

(yeah, Bob, i'm thinking of you)

Would you have a 'play' with this and see how you get on. i know it is not
lubuntu base system stuff, but the 'advanced' and 'expert' areas are still
completely empty. If the team would rather them be on the 'un-official'
How-To's over at http://forum.phillw.net/viewforum.php?f=18 I'm more than
happy to pop it on there with the usual warning "Not Supported"
Whilst I do not want the devs distracted from important things, "children
will play" and some of us wish to expand on the base install.

I'd also appreciate the solution to
http://forum.phillw.net/viewtopic.php?f=18&t=101 which was mentioned on the
mailing list, but told that it needs more (That solution was from a dev, so
it needs making into what we mere humans would understand). If anyone wants
access to any "How To's" over on
http://forum.phillw.net/viewforum.php?f=18 that
are either in preparation for transfer to the wiki area or should just
remain on that area you can contact me. Any person who has signed up for
C-o-C on launchpad is automatically given moderator rights on that area so
as to able to edit anything, just as we have with the lubuntu wiki pages.

I'm sorry I've not been about as much of late, I'm getting the finer points
of accessibilty for a site sorted out, expect me to back nagging about ocra
and lubuntu :-)

Regards,

Phill.
