Drupal modules are contributed back to the open source community on Drupal.org.
Wysiwyg Linebreaks allows users of wysiwyg editors (such as TinyMCE or CKEditor) to save and open markup from their website with linebreaks instead of <p> and <br /> tags.
Honeypot uses both the honeypot and timestamp methods of deterring spam bots from completing forms on your Drupal site.
A lot of people use form spam prevention methods like CAPTCHAs or math problems that require extra user interaction, and cause some users to have trouble filling out online forms. For most small sites, something as complicated as a CAPTCHA is not really necessary anyways. Therefore, I wrote the Honeypot module, which adds invisible form elements to selected forms, and checks to make sure the form elements are not filled out by spam bots.
