<p>As I understand your description, this would be a pure software / how-to question.  As such, it would be off-topic.  </p>

<p>There is, however, a <a href="https://stats.stackexchange.com/questions/tagged/glmnet" class="post-tag" title="show questions tagged &#39;glmnet&#39;" rel="tag">glmnet</a> tag.  You could leave comments (where it seems appropriate) on tagged questions.  You could also edit the <a href="https://stats.stackexchange.com/tags/glmnet/info">tag wiki</a>.  Moreover, in answering questions with the tag, it might be fine to mention the package along with the disclosure that you are the author.  </p>
