 Unsure where to begin contributing to Poly? You can start by looking through these beginner and help-wanted issues:
 
-[Beginner issues](https://github.com/TimothyStiles/poly/issues?q=is%3Aissue+is%3Aopen+label%3A%22beginner%22+) - issues which should only require a few lines of code, and a test or two.

 ### Security disclosures
 
-If you find a security vulnerability, do NOT open an issue. I've yet to set up a security email for this so please in the interim DM me on twitter for my email [@timothystiles](https://twitter.com/TimothyStiles).
+If you find a security vulnerability, do NOT open an issue. Instead, email [email protected] with a description of the vulnerability and we will get in contact with you ASAP.
 
 In order to determine whether you are dealing with a security issue, ask yourself these two questions:
 
 * Can I access something that's not mine, or something I shouldn't have access to?
 * Can I disable something for other people?
 
-If the answer to either of those two questions are "yes", then you're probably dealing with a security issue. Note that even if you answer "no" to both questions, you may still be dealing with a security issue, so if you're unsure, just DM me [@timothystiles](https://twitter.com/TimothyStiles) for my personal email until I can set up a security related email.
+If the answer to either of those two questions are "yes", then you're probably dealing with a security issue. Note that even if you answer "no" to both questions, you may still be dealing with a security issue, so if you're unsure, shoot an email to [email protected].
