Modification to Tag Cloud
I modified the tagging plugin, since each tag in the tag cloud of a page that had been filtered with another tag had a link that filtered the result with the disjunction of the two (or more) tags. I believe this might be driving crazy the robots of the search engines, as the number of links that points to a given page became essentially infinite. I just found and commented out the lines

            ((($link_cloud eq 'blosxom') and 
              ($filter_tags !~ /(^|,)\Q$tag\E($|,)/) and
              $filter_tags) ?
             "$l_filter_tags," : '').

Order of paging plugin
I realized that the paging plugin of blosxom has to be executed after the stories have been filtered by the find and tagging plugins. Otherwise, the number of stories to display comes out wrong and the last one is repeated unnecesarily. Thus I ran rename s/^/50/ * and mv 50paging 75paging. The fix seems to work.

Find Plugin
I added the find plugin from the registry to my blosxom blog.

Paging
I installed the paging plugin for blosxom, as I already have 36 stories and soon they won't fit in one page. I also tried the paginate plugin, but it had some errors.

Instructivo para este blog
Escribí un instructivo en el wiki del ICF para usar este blog; quizás un poco largo.

Errors in blosedit
Today I installed wbcaptcha and had to modify the flavours story.html, foot.writebacks, etc. I made various experiments and when I finished, blosedit stopped working. I didn't understand why, but after removing its cookies it seems to be fixed.

wbcaptcha
added wbcaptcha and tried to configure it. I made some tests with comments. It seems to work now.

Added hitcounter

I added the hitcounter plugin, version 0.5 to my blosxom installation, but I believe it had a bug. I replaced the lines
$path =~ s/(\.$blosxom::flavour)$//; # strip flavour from end of path
my $suffix = $1;
by
my $suffix='';
$suffix = $1 if $path =~ s/(\.$blosxom::flavour)$//; # strip flavour from end of path
Otherwise, $suffix would get garbage when there is no explicit flavor. For that reason, my directories were not accumulating hits.

Tagging plugin
I added the tagging plugin. Seems to work very nicely.

regular expressions in blosxom
I found that blosxom allows some kind of regular expressions in the url/paths. If try to reach .../a (... is the url of my blosxom cgi) I get all directories starting with a. If I just want those files under /a, I should write .../a$ with $ as the end of string. The same holds if I add an index, as in .../a/index.html, which might serve more files than .../a$/index.html. I tested some other re constructs in the url, such as .../a[^b] which would give me all files under directories /ac, /ad, etc., but not under /ab. The regular expression that doesn't work is /a.*. The asterisk is mistaken as the flavor as it goes after the dot. This feature allows a lot of flexibility, but it worries me somewhat: is it dangerous?

Instalation of blosedit
I installed blosedit 2.1 today. To make it work I had to comment all the @default_template variables. I also added -charset=>"utf-8" to all instances of cgi->header and save the cgi file as utf-8 and replaced encoding to utf-8 to get accented letters and latin symbols consistently. I still have to understand how to use the templates.
