1. Messenger FX
   
   Messenger FX is a web-based service that lets you access the MSN instant messaging network without having to install anything on your computer. The access is protected through encryption and the interface is available in multiple languages. There is no possibility to talk to contacts that are on other IM networks. Free to use.

2. BigFileBox
   
   BibFileBox is a web-based file hosting service that you can use to upload and share your files with other people. After you choose whether you want to upload a file using the Java drag-and-drop facility or the click-to-upload interface, you can upload as many files as you want and, when done, you can create "tokens" to give people permission to browse/edit your files. You can also choose the duration of the token. Free for up to 50 MB or see plan comparison.

3. JKN
   
   JKN is a web-site that allows you to add notes on a web-page and to share them with anyone. After you insert the URL you want to annotate, you can decide how you want to share your notes with others (link, email or blog), and start typing on the selected page as it was a normal blank page. Then, depending on the sharing method you chose, you will be given a URL to share or you will be asked for your contacts' emails. It is free to use and requires no registration. Beta.

4. DrawHere
   
   DrawHere takes a slightly different twist on the website annotation paradigm by allowing users to literally draw directly onto a website that they are visiting. Clicking on the bookmarklet opens up an image editing palette to the side of the screen. This palette features layers, opacity, brush size and a color spectrum. Annotated pages can be saved and shared by email or embedded into your blog. Different users annotations can be browsed through from a separate window. DrawHere can be activated via a bookmarklet, from the DrawHere website by entering the URL you want to draw on, and can even be included as a button on your web-page. Free
