In Regards to POST DELETES and EDITS
First the issues we have run into over the years...
A person with a lot of posts in not just one thread but many gets upset and something and then chooses to "take his ball and go home". To do this he looks for every post he has made and mass deletes them thus disrupting every thread he removes posts from. Doing this not only has that result, but the result of search engines having content that is no longer found on our site.
Allowing to edit a post, the member can do the same thing. How many of us have seen a post where all it is is a "." in it? That is where someone could not delete the post, or missed he could, and just wiped the text with a "." Poof, same negative result.
I can remember one member that removed over 100 posts inside a thread before we got wind of what was happening and stopped it. Now that as disruption. Members were ticked!
I know some of you that have been here for some time have seen this more than a few times.
However, with that said, I have expressed a number of times to the team about the threads where the first post is used more or less as an updated index. These are VERY IMPORTANT and we are looking to see what we can do with special permissions to allow the post to be edited. However, you see, the concern is that member, in long time good standing, also get ticked off and POOF, it's gone with the "." in the post. (Now I know none of you get upset like that from time to time.

)
So...Enter the New Feature: ARTICLES... Maybe this will help...and I hope it does. We now will have Articles, a Wiki if you will, that can not only be edited, but edited by many based on rules set into place (post count, time on site, granted access by the Article starter, etc). So the "special first post" in these special threads can be moved into a Article and thus you now have a reference point not only picked up by Google and the others indexes that now see it it is tagged as "special" item, but it also can be listed and categorized for the members within AVS. All the links you may have in the first post that links to other posts in thread, all can be their. Then we just update the first post in the thread to reference the new Article.
This is a totally new feature for us and I really hope it helps out with some of the long threads. Keys posts in the threads can actually be moved into the Article and maintained. (Aka...Wiki)
I hope that came out right and that maybe you can see we are truly looking to the future of the site and this was surly talked about and still is being talked about.
Thanks all.
