I have, as I have time, been adding content to the tags so they indicate appropriate info with what they are tagged to. Yesterday I tagged another five or six tags, but only one tag was updated. I'm not overly worried it, but was just wondering if there was just a backup in the review process, or if I have exceeded the amount of work I can do in this area? Mind you, I'm just trying to get some maintenance stuff done with the site to hopefully make it more appealing and useful to all. If I'm only allowed to do so much in this area, by all means I'll not do anymore.
Not sure exactly if the system has an auto-halt on editing activity but (and this is for your account specifically) if you go here you can see all recent account activity and see what became of any suggested edits you have put forward.
More specifically it seems your last tag edits were rejected for being blatant copies of some other source (most likely wikipedia I assume)
We reject this on the excerpts because there is no way to attribute wiki as the source of the items. It is ok to use it in the Full Tag Wiki but because the excerpts have such a limited character range it is much easier to just blanket deny.
For the excerpts we try to encourage original content as that is the summary that appears when a user is hovering over a tag. It is meant to give a quick description of what the tag is about and used for. If they choose to know more they can click on the tag for that.
