The original idea was to cover those things where no version was given. A lot of those entries are not maintained that well, you see, and many are hacks with just one URL. Many times modules work on lots of versions.

But I agree it's a problem and "Download Development version" is probably better.

Currently, no, there is no plugin system for the center column of the tags pages. There should be.

What you could do is copy the flick or youtube block and create a special block that works similarly to detect the current tag on the page and to create the links to wiki pages.

Unfortunately there is a problem with general blocks on tag pages because they don't yet have their own contexts. This should be fixed in Moodle 2.0 when we revisit the whole page/blocks structure.

Since roles are dynamic, and there can be many "teacher roles", you just need to pick the capability that is relevant for you in that context.

eg:


$context = get_context_instance(CONTEXT_COURSE, $courseid);

$users = get_context_users_bycap($context, 'moodle/course:update');

print_object($users);
