I have found that there is no better piece of software for writing blog posts than Windows Live Writer. It is a free, superbly designed piece of software that destroys the competition.
If you are going to write for GeekBrainDump.com I would highly suggest you take a look at it to make all of our lives easier.
You can download it from here: http://www.microsoft.com/en-us/download/details.aspx?id=8621 . During installation you’ll be asked to install other Live software, but all you need is Live Writer.
If you do not yet have an account for GeekBrainDump.com simply email Post@GeekBrainDump.com and one will be set up for you.
Once Live Writer is Installed You Select the Blog Account Drop Down Menu and select “Add Blog Account…” if you were not asked during installation.
Select “WordPress” from the radio box options…
Use www.GeekBrainDump.com as the Blog address and then use the Username and Password for your account…
You will be asked if you want to download the Theme. Generally this fails so I would say “no”, but it doesn’t hurt anything of you do.
You are then given the ability to give the Blog a NickName and you click finish.
You cannot PUBLISH posts to GeekBrainDump.com from Live Writer because of permissions. You must select “Post Draft to Blog”. Once you have done this we will review your post and then publish it.
