I would like to improve the tagging of my questions as I see that the tags are edited many times. Is there a way of comparing the new tags with the original tags without keeping a record of the original tags?
Look at the edit history by clicking on the time-stamp listed next to the most recent edit, or by going to http:// [meta.] judaism.stackexchange.com/posts/ [post ID number] /revisions.
For this post, the revision history is at https://judaism.meta.stackexchange.com/posts/1073/revisions where you can see the tags I added at 2012-05-06 10:30:35Z SST (StackExchange Standard Time).
