Using flags
If you've written something useful, for instance, you might want to flag to it for later reference. Flagging will 'snap' to the message line with a link. Working example above. To flag, type [flag]nameofflag[/flag]. Then when the message is needed you can type this, [flagurl]#nameofflag[/flagurl]. You cannot have 2 flags with the same name, typing a random number will make sure you don't. The flag name is in the tooltop (hover your mouse over the flag).

Encrypting email
To encrypt your email address so it can't be harvested by spiders, replace @ with [at]. For example, Help[at]PublicWarehouse.co.uk. When the email link is clicked on, [at] will be replaced with @.
