With Apture, you can add multimedia to your blog with one click. You can use the Apture Media Hub to access multimedia from a range of sources all in one place — no more copy and pasting codes from different websites.

Apture suggests the most relevant content based on what other members of the Apture community have been linking, so you can find the most relevant content even faster. You can even resize the content intuitively by dragging from the bottom corner of any embedded item.

Until now, links have only allowed you to reference one thing at a time. But Apture let’s you link several different types of media together, so your readers can simultaneously see, hear, and read about a topic you care about.

Fire Eagle is a site that stores information about your location. With your permission, other services and devices can either update that information or access it.

Fire Eagle allows you to share your locations with other sites and services safely through a secure server – you are always in control. You can decide to share your location with any site that can use it, and even choose how much detail to give that application (exact point, neighborhood, city, state, country).

Now you can display your current location on your WordPress blog by using Fire Eagle for WordPress. it installs as a WordPress widget, which displays your last know location from Fire Eagle in your side bar. This has only been tested on WordPress version 2.5.1 (and 2.6 now!) with PHP Version 5.2.5, it should work on earlier versions of WP that allow widgets, but has not been tested yet. Your WP theme needs to support Widgets for this to work.

Requirements: WordPress version 2.5.1 or higher

WordPress already offers naturally a comfortable possibility to publish articles delayed. The advantages of this convenient function are obvious: Posts can be created in advance and will automatically be published a few days later or on midnight – even if you are not at the pc. wpSLEEP is based on the same thought and actuate parts of a post as the author likes them to.

In the originated post, text passages, graphics or other elements are marked up to sample and are provided with a start- and / or end date. After saving and publishing of the post, the marked part is only viewable during the time span specified (from 01.10.2008 1 pm until 31.12.2008 6.30 pm for example).

Examples are also graphical banners or text links, which are booked for a certain time. Accordingly paragraphs or chapters can be taken first off- and at later stage taken online again, just one specifies. Variations are nearly unlimited! And there is no database necessary for wpSLEEP!
