Hey! Using Google Chrome or Chromium? Here are some search engines which might be useful. You can add them by going to chrome://settings/searchEngines in a new tab and scrolling down to the end of the "Other search engines" category.

Name: Weasyl Search

Keyword: wzl

URL: https://www.weasyl.com/search?q=%s

Example: wzl foxes (Searches for foxes on Weasyl)

Name: Weasyl User

keyword: wu

URL: https://www.weasyl.com/~%s

Example: wu makyo (Go straight to my profile)

Name: Weasyl Submission

keyword: ws

URL: https://www.weasyl.com/submission/%s

Example: ws 147052 (Go immediately to that submission; I have a friend that likes to reference IDs, so maybe not useful for everyone!)

Via @Draikyr on Twitter: all of these work on Mac for Alfred's custom search: just replace %s with {query}
