[sclug] Wiki editing?

[John Barron]

Q1)
When I go on to the wiki and make revisions, why is it that I seem to get a:
<!-- Toms debug Comment old time 1146915751 -->
entry mysteriously appearing at the foot of the page I was editing???

seems to happen if I've used the Preview button before saving, but I don't 
seem to be able revise it and remove it, it just changes the number every 
time.

Q2) 
How do I "rollback" a revision to a previous version, e.g. if the page has 
been trashed in the meantime or something like that?

thanks
John
