Add more links to your profile page!

twhois:

Our crawling system can not be perfect of course and many of you recently complained about missing important links in your own home pages on Twhois.

During last days we managed to improve our editing script, increasing the personalization possibilities by enabling the ‘Add profiles’ button.

After you logged in via twitter and pressed the button, it would open a nice popup containing a simple form. Needed parameters are the Link, a Description and the Type of url you’re adding. If you select a social website you probably need to complete even the last field (Username).

After submitting the form you should be able to see your brand new profile at the top of the list of your links.

This feature is highly experimental so please expect some bugs and remember to fill out feedbacks!

We obviously understand that even ‘delete’ and ‘sort’ functions are needed and we’re working to them right now!
