How?

[Erasmus]

How do you put a quote in your sig?

[Desuetude]

You can highlight whatever it is you want to quote and use the quote button which looks like a speach bubble and says "wrap" when you hover over it. Also if you want to quote a post then click the quote button on the selected post and just copy the whole thing that comes up and bung it into your sig.

Click the quote button on someones post, and copy it to your clipboard and then post it in the "Edit your signature" area.
