+
Adding a tag for a course
+
+
Logged on users may 'tag' courses.
+
+
A tag is a shortcut or way of navigating to your favourite things.
+
+
Not only can you tag courses, but you may also tag your blogs, or even your own profile.
+
+
Clicking on a tag will take you to a page listing all the things associated with that tag.
+If the tag is a popular one you will be able to see what other things other users have associated
+with that tag.
+
+
You may add as many tags as you like. While it is recommended to only add one tag at a time,
+more tags could be entered on one occasion by seperating the tags with a comma.
+As you are adding a tag you may notice a word appearing in the background where you are typing.
+If this word is what you want as your tag then you can click on the little
+arrow next to the entry box to save typing the that word (and don't forget to click submit to save).
+
+
Tags must be more than one character and may be up to 50 characters long.
+Please note that while extended characters are allowed (e.g. French acute
+accented characters or Chinese characters), special characters will be
+stripped (e.g. "',\,_,<,-,~,?").
+Also note that tags cannot be pure integers or float number (e.g. 1 or 1.11)
+but number and letter combinations are fine (e.g. 1a).
+Finally, commas cannot be used in tag names, as these are separators between tags entered.
+
+
Don't forget to click the 'Submit' button below to save your new tag.
You will only be able to delete a tag entry that you have previously created.
+This allows you to tidy up those mis-spelled, or out-dated tags. Please note that
+deletion will only delete the tag if no other user has tagged something else with it,
+otherwise deletion will just delete your association of that tag for the course.
+
+
Deleting is done by highlighting the tag you wish to delete under 'Select...',
+then clicking the 'Submit' button below.
A note about the tag count. Hovering the mouse over a tag will reveal a tag count message
+like '2 things tagged with ...'.
+This count (number) will vary depending on where the tag is being displayed at the time.
+
+
The 'More tags' page (and the tags block) can display several different selections of tags
+- for instance 'all tags' or 'my tags'.
+The count displayed for a tag under 'all tags' may be different to the count for the same tag
+displayed under the 'my tags' or one of the other selections.
+This is because when 'all tags' is showing, all tags for courses, blogs and user profiles
+are displayed and counted.
+Where as when 'my tags' is showing, only your own tags for courses you have tagged
+are displayed and counted.
+So the count could be quite different for one tag under different sections.
+
+
Of course the size of the tag is also a clue to the count. The bigger the font size for the tag the
+more popular the tag is.
+
+
In fact it is easy to re-order the tags displayed by popularity, using the link provided.
+And the tags may be re-ordered alphabetically or in date of creation order as well. Try it.
