First off all - thanks for the hundreds of customers making Poster Stack one of the most successful commercial Stacks for RapidWeaver 
Poster Stack v1.11 gives you the much requested possibility for online adding and editing of blog posts. This is internally available for some time now (my blog is based on it) and come now as a free, all-you-can-eat update for every customer. No limits in publishing or domain usage. Just go out and make love 
ehm create blogs 
No worries: You don’t have to start from scratch. You are able to add online posts on top of offline posts. Mixing of online and offline posts will be possible in a future major upgrade.
Read more here in the tutorial (also based on Poster) or watch the video.
Happy blogging!
