Editing rights on docbook wiki

Hello,

I am currently going through the wiki and especially with regards to 
tools am finding things that could use updating (which I would very much 
like to do, being the very humble contribution I am able to offer to the 
project at the moment).

Following the advice on the front page to contact someone in the 
UserGroup to obtain editing rights, I asked Dave to add me to the 
editors, but he does not have rights to do that.
Could someone who can please add me - and should the instructions be 
corrected?

And right before I begin doing anything:
how should dead links be handled (I've found a few that should point to 
online resources) - annotate, research where the contents may now be on 
the Web, or just remove?

Thanks!
Nathalie Sequeira
