| nxpfan | 0:2a57fec4e078 | 2 | Update: 21-06-2010 |
| nxpfan | 0:2a57fec4e078 | 3 | The basic authentication service for twitter is going down at the end of the week. |
| nxpfan | 0:2a57fec4e078 | 4 | To continue using that program, the code has been updated to use http://supertweet.net which acts as an API proxy. |
| nxpfan | 0:2a57fec4e078 | 5 | Simply visit the website to setup your twitter account for this API. |
| nxpfan | 0:2a57fec4e078 | 6 | See: http://www.supertweet.net/about/documentation |
