- By default, you will be subscribed to receive email notification about new posts, comments, etc. If you prefer not to receive email, you can manage your subscriptions from the subscriptions page. (Another way to get updates is to subscribe to the RSS feed.)
- You can ask questions by leaving a
**comment**on a blog post. If you’re feeling apprehensive about asking questions in public,*feel free to register under a pseudonym*. - You can include mathematical notation in your questions using standard $\LaTeX$ syntax. For instance, the expression
`\int_M K dA = 2\pi\chi`becomes $\int_M K dA = 2\pi\chi$ when enclosed by a pair of dollar signs - For fun, you can associate a picture to your profile by registering your email address at Gravatar.com.
