Login on Microsoft Community Server websites
I don’t know if you can find them, but I have no idea how to get to the login page and/or register account page via some link, on weblogs.asp.net and blogs.msdn.com. A lot of blogs have anonymous comments turned off, therefor you might want to register or login. Another reason is subscribing to new comment, so you’ll get an email when a new one is added.
Luckily they’re using Community Server, so those locations are the same everywhere. If you want to know, these are the locations.
weblogs.asp.net
blogs.msdn.com
I tried this a while back and IIRC creating a new account was disabled, however it looks like weblogs.asp.net shares member info w/ *.asp.net, so you can create a new account from the other pages as well and it will be shared across the entire TLD.
Regardless, good find…quite a few asp.net bloggers have anon comments disabled so this’ll help out quite a bit!
