Custom Links in User Profile

I want my users to be able to insert links in their profile, but
obviously they can't use html.

I want to solve this by allowing them to do
[link=""][/link]. Any idea how I would go about


I would consider using Textile or Markdown. Take a look at the
RedCloth gem.

linker =\[link="(.*?)"](.*?)\[\/link]/)

<%= @user.profile.gsub(linker){|m| "<a href='#{m[0]}'
class='whatever'>#{m[1]}</a>"} %>
