I’ve just started using Windows Live Writer, and like many other programs (and websites) it would create a double line space every time I hit the enter key, the solution:
Hit Shift + Enter when creating a new line.
Big thankyou to John Kavanagh as I found this solution on his blog :)
I can’t find how to add WordPress tags to my posts through Live Writer though…? Only tags from external providers, e.g. Technorati.
