Got (SF-LUG & BALUG) Wiki? [DO NOT REPLY-ALL unless you're subscribed to BOTH lists!]
So, the http://%5Bwww%5Dsf-lug.com/wiki/ wiki stuff that was used by both SF-LUG and BALUG (and apparently some others too) ...
Have a look here: https://secure.balug.org/wiki/doku.php?id=balug:wiki (or here: http://www.wiki.balug.org/wiki/doku.php?id=balug:wiki or here: http://wiki.balug.org/wiki/doku.php?id=balug:wiki ) (for https://secure.balug.org/ at least for now you'll want to accept BALUG.org's "snake oil" certificate ... want a trust path to it? See: http://www.balug.org/https.html )
Essentially, what was on/under http://%5Bwww%5Dsf-lug.com/wiki/ is now available (at least somewhere - some locations changed) on the BALUG wiki site.
Note that non-BALUG materials may just be there "temporarily" (i.e. they may move elsewhere some day(s)/week(s)/months(s)/year(s) in the future), but at least for the time being they can generally be used (and updated, etc.) on the BALUG wiki.
Also, if you set up a new registration on the wiki, or logged into the current or former sf-lug wiki via http (rather than https), and haven't already changed your password via https and only used it over https, I'd recommend changing your password on the wiki via https.
