You can update your Blast-FM status from a few places:
To reply to one of your buddies status', you must first type @ symbol, then the username of the person who you are going to reply to, and then the message. Example: @johndoe hey!.
If you prefer to send a private message, you must first type ! symbol instead of the @. It works like replying to a status, but with a different symbol. Example: !johndoe ok, see you there!.
You can access many useful functions by hovering over your avatar in the top navbar and then use the drop down menu that appears. New!
Have you got a Twitter account? Then you can keep your followers informed at the same time as you read your posts. Just add your account at the Twitter tab in the settings page and you'll be able to do it.
You can reply to your Twitter friends' notes just using the % symbol instead of the @. It works like replying to a status, but with a different symbol. Example: %Marquitox that sounds good!.
All users can customize their profiles. Take a look at the settings page, where you can upload your favorite background image, your avatar or choose a different theme.
If you want, you can send a note every time you update your WordPress blog. Blast-FM can do it automagically. All you need to do is install the plugin, type your username and API Key, and that's all. If you want you can customize the message.
You can also put your last Blast-FM note inside your blog's sidebar, using Blast-FM for WordPress.
