I was looking on the Area 51 site, and I can see my total rep for all sites by looking at a proposal I'm committed to, but it's not anywhere on my profile. Is there a better way to find out what my total rep is?
You can use the app created by George Edison for just this.
Take a look here.. You can bring up your rep for each site and look at it separately, or you can see your total rep for all properly associated sites.
For example here is your total rep, total graph, and assorted other:
If you go here
it will display all of you accounts but it doesn't show the overall total rep as a single figure - I think you'll have to get your calculator out.
Might be worth raising a feature request and ask to get it added on to this page.
