I have forums in my web. I have a field in my database in my posts table
that is a textarea.
I would like to save things like press enter or use bold when I write a
message in the forum, but it is not possible only with what an scaffold
gives.
I think there are some javascripts that can help. Which is the best
idea?
Look at Textile or Markdown to make it really simple. I think there
might be a javascript editor to add the tags for you, but I would
recommend one of those two for simplicity's sake.
