That’s the word I was looking for – dynamically, I guess. The plugin in use checks every X minutes for unseen content posted in Twitter by user U. If there is new content, it creates a new post in a category of my choice. I have no further information about the behaviour of this plugin.
Any ideas for a workaround? This site is not that crucial so even an automatic onload zoom-in – zoom-out would do the trick I think, if technically achievable.
