g.d.o revisions tab for wiki pages

On groups.drupal.org, wiki pages currently display a byline for the original author. This gives the impression that the original author wrote most of the content of that page, but this is frequently not true (it is a wiki after all). There are two main perspectives here:

1. You are the original author and someone comes along and substantially changes what you have written. It can be very disconcerting to receive credit for words you have not authored or perhaps not even seen. In fact I dislike this so much, I think it would put me off starting another wiki page until this has changed.

2. You are putting in a lot of work to improve the contents of an existing wiki page. Perhaps you don't care about receiving the credit (that's not the motivation for helping), but it's not very encouraging to always see the original author get credit for parts of work they haven't done. That's a much smaller issue than the first though. It's much worse to receive credit you don't deserve than to lose it. Still, I'm pretty sure this discourages people from contributing on these pages.

So the request is to simply get rid of the byline.

Also, the revisions tab would be useful :)

Thank you.
