padlock returns

A couple of months ago I spend some time modifying the WordPress ViewLevel plugin slightly to include in this blog. At the time, the idea was to restrict the readership of certain posts (such as info meant for master-class students etc.). In the sidebar these posts are prepended by a padlock sign (together with the appropriate view-level). In the main window these posts do not show up unless you are logged in and have the fitting view-level.
I hope that this tool may also prove useful to combat spam-comments. Ideally, a weblog should be configured to accept any comments but if you have to remove a 100 or more link-spam 'comments' each morning to keep your blog poker-free you have to play defensive. Unfortunately, WordPress is not very good at it. Sure, one can opt to put all comments on hold, awaiting moderation but (1) this is unpleasant for genuine comments and (2) one still has to remove all spam-comments manually from the moderation-queue. In the end, I had to close all posts for comments to be spared from poker-online and texas-online rubbish.
However, I appreciate comments and suggestions especially at a time when this weblog is changing. So, if you are working in either non-commutative algebra or non-commutative geometry and want to give your suggestions, please get yourself a login. I know, I know, it is a hassle with all those nonsense passwords but if you are accessing this weblog from just one computer you only have to remember it once (I forgot my own password but can still post here…). I will then raise your ViewLevel from the default 0 value to at least 1 so that you can read and comment the padlocked posts. If you then want to make a comment on other posts, please use a nearby padlocked post.
Today, I ask for suggestions for a good LaTeX book-style. At the moment my favourite is the CTAN thesis-package but surely there are better packages out there!

again : this idea came to nothing!
