Someone with more admin access than me will have to finish the job, but check this out:
CLICK HERE:
BThis will take you to entries that start with B.
Now we can place links for each letter either on the Categories page or the main page, that will let you browse by letter, instead of clicking 'next 200' for all eternity! Simply take this url:
http://superman.nu/wiki/index.php?title=Category:Entries&from=Band replace the letter B at the end with whatever letter you'd like to link to.
On the other hand,
http://superman.nu/wiki/index.php?title=Category:Entries&until=Bwill show only the A entries. The problem right now is showing one letter at a time (except A.) I haven't figured it out yet, but doing that would make the process slower anyway. Better to start with the letter in question than to limit to only that letter.
