Credweb CG Chair Election

The group database has been fixed, so it's back to showing me as chair, 
after showing no chair from 13 Apr 
<https://web.archive.org/web/20210413003527/https://www.w3.org/community/credibility/> 
to 16 Jul 
<https://web.archive.org/web/20210716090217/https://www.w3.org/community/credibility/> 
when Madilyn stepped up.

Let's use this as a chance to hold chair elections using the process 
suggested in the CG Template Charter 
<https://w3c.github.io/cg-charter/CGCharter.html#chairs>.  14 days for 
participants to announce their candidacy, then 21 days to vote. While 
this is happening, I hope we can shed more light on how this group might 
proceed.

I've set up a wiki page 
<https://www.w3.org/community/credibility/wiki/Summer_2021_elections> 
where candidates can list themselves, so we don't miss anyone in a 
possible flood of email. Please also send an email to this list starting 
a new thread where you can take questions about your candidacy.

I'm not sure if I'll run for re-election, but if I do it'll likely be on 
the platform of not holding meetings or having much activity unless I 
personally see a path to the group delivering value. If you have a 
different standard in mind, and are willing to do the work, please do 
step forward.
