ShowDocument

http://www.showdocument.com/ds/main.jsf Do you have to conduct a Net meeting or Web conference where you also need to share documents, work the whiteboard, or discuss particular elements on a Web page—all collaboratively, across continents? Try this file-sharing and Web-meeting platform. You can set up any of the above and mail the join-in code to your cohorts. They simply arrive at the site, type in the code to join you online for synchronized co-browsing, commenting, or editing. Any uploaded file or Web page can be marked with a pen/highlighter tool, etc. during sessions.
CopyTaste
http://copytaste.com/
This Web tool allows you to create specific private URLs for data that you want to share. All you need to do is copy-paste what you want to share—be it quotes, stories, tips, or uploading an image or video—and simply mail people the specially generated URL. You can make your page private or public, allow comments and post formatting-rich text. Sadly, the site is vague on instructions and this can be galling. No registration required.
MonkeyOn
http://monkeyon.com/
Getting things done by people can be quite a job sometimes. Here’s a website that takes on the onerous task of constantly auto-prodding (politely termed reminding) them into action until the deed is done. Quite simply, the tool allows you to create a to-do list (along with associated deadlines) for others. MonkeyOn then keeps sending them reminders (termed “monkey on their back”) until they complete the task and activate a kill process to silence the reminders. Registration is very simple. No monkey business, this.
PDF to Excel

http://www.pdftoexcelonline.com/Culling data from tables in a PDF file can be tough when it involves tedious key entry. PDF to Excel makes the task of creating editable XLS files faster and easier. It can create reusable tabular data that can be edited in Excel, OpenOffice, or Google Docs. All you need to do is go to the site, upload the PDF file you want to extract table data from, hit the “convert PDF to XLS” switch, and enter the email ID where you want the XLS sent. No registration, no verification needed.
OldVersion

Software upgrades are good. But sometimes the bloated features do not agree with your PC’s working capabilities or your relearning abilities. Or you may have developed an affinity to a particular feature that has been killed off in a subsequent version. Instead of sitting and cursing coders, check out this site that gives you older versions of various programs. These range from instant messaging (IM) to security, multimedia to utilities, the Internet and enterprise-level stuff. Very useful also if you have an older-generation working PC stowed away somewhere.
