Recommend an SEO online annotation/collaboration tool?

[RCF]

I'm looking for an online collaboration tool that will allow me to make notes on a Web page and share it with team members. I'm looking for something like Diigo, but I want a tool that will allow me to comment on the title tag, meta description and maybe even alt tags.

Is there such a thing out there?

Thanks!

This may not be a good answer, but at a time there was a chrome add-on that you could analyze meta tags, but at the same time there was a sticky note, it would then allow you to email, or save file after you commented on it.  This may not be 100% what your looking for, but you may want to check it out if you can't find anything else.  I wish I knew what it was called, but this was about 9 months ago I seen it and I didn't have a use for it at the time, so I got rid of it.

Have a great night.
